On the keywiz... I understand that randy wants to have the maximum number of inputs, but as you were leading towards it really isn't necessary. His excuse for leaving out the leds and the pass-through is mainly a speed/limiting the number of inputs issue.
That sounds good, but has nearly everyone on this thread has said, there aren't any issues with the speed on the ipac, nor the number of inputs, nor the shift key feature (except for it's odd mapping of escape of course). Also there isn't an issue with remapping, as the latest generations of the ipac allow for on the fly key remapping without any software as well, it just works differently.
So without picking sides on either one here is what we have........
Two similar encoders, with one (keywiz) lacking several nice features in lue of more useless, different features (no delay on the shift key and more inputs). But the keywhiz is cheaper.
So if you are really budget conscious and/or want a cheap 4 player layout then get a keywiz, otherwize get an ipac.
From where I sit the better performance of the keywiz is great, but totally unneeded as the ipac already does a perfect job performance wise.
I wish randy the best of luck, and I honestly think it will do well because of the lower cost, but the selling points he is giving really aren't selling points imho. Even if they were the pass-through option and usb support is really a key selling point ot the ipac and the lack of those features is more of a downside then any new advantages.
Anyway, I'm not trying to beat a dead horse here, I just think the consumer should understand the benefit (or lack there of) these new features will actually have in practical setups. Again, both are great products and I don't think you would really be "jipped" by buying one over the other anyway.
Howard, your points are taken, but I have to respond to this.

I think that by failing to mention some of the other features in your comparison, you are selling the KeyWiz short.
You mention that no-one has ever had any problems with performance with an IPAC, but it isn't used much in a 4 player configuration either. The larger buffer and extra inputs does make this a possibility with the KeyWiz, and because of the way it is designed, it should work quite well for that application. In other words, it's up for the task.
You also don't mention key-repeat. From what I understand, the IPAC does not do key repeat in PS/2 mode. The first time you try to scroll through a large list, you'll see the value of this.
You also gloss over the software support. As I haven't really given a complete feature list, I'll take the blame on that one. The KeyWiz software is more comprehensive than any other out there for this type of device. You can set up and name a profile that will allow you to edit/upload the new character definitions and automatically launch the application associated with it. Automated programming and launching of applications can even be done from a shortcut or the command line. Did I mention that, with the exception of the command line stuff, you can do all of this without the need to drag your keyboard out?

And I am curious about on the fly codeset switching on the IPAC. Could you elaborate a little?
I'd also like to say that the things that are not valuable to you, might be of great importance to someone else. And likewise, the things I see as valuable, others may see differently. For instance, I don't care about a keyboard pass-through, as I have a USB keyboard. I also don't care about USB compatibility, as again, I have a USB keyboard. And my
personal opinion is that I don't want USB keyboard technology for my controls because I don't feel that it's up to task, but I'm sure it's fine for others, especially people with MACs who have no other options. As for LEDs, I don't use them (as most don't), but if I did, I would want to be able to select the type I wanted to use and not be limited to the low current/output variety. But again, that's just my
opinion.
So you see, all of those "valuable" features you mentioned have no value at all to *me*

While I don't feel that you aren't taking sides, I do appreciate the comment about not getting "jipped" either way

I won't tell anyone that the KeyWiz is the solution to every situation (just ask Tiger-Heli). They have to do what is right for them by weighing all the factors. Being able to sleep at night is more important than taking someone's money for something that may not serve their needs. Otherwise I could have played "status quo" and charged the going rate for these devices, but that's not what was important to me.
I really was hoping this wouldn't turn into a KeyWiz vs IPAC war. They are two different products each with merits/downsides of their own, depending on the perception/needs of the individual looking at them. But based on discussions I have had and the orders I have recieved so far, I'd say that your perception isn't shared by everyone.
