**UPDATE**
Hello again everyone! I thought I'd give you all an update on what's been happening.
I took the advice from many in this thread and put it to some good use. I believe I've put to rest the thought of building a cabinet from scratch....at least for now. The reason is because (again...right now...) I will only do this once, I don't have the tools (which I'd have to buy) and I'd have to rent a truck each time I needed wood. The hassle factor alone would be enough to sway me away.
Choice #2 is still alive and that it to start with a cabinet already built. I've had a couple of conversations with DrMoonSparkle, and he sure seems like a super nice guy, but he seems to keep insisting that I drive up there to look at the cabinets he has. Even when I hinted of a couple of his E-bay auctions would work quite well if we could come to an agreement on shipping, he still said I should drive up to see what he has. I understand why I suppose, but I'm not too keen on driving 200 miles (round trip) to do that.

Last Monday, I called tntgame.com, and as I had indicated previously, left a message on their answering machine. This past Sunday night, I again took the advice from here and followed up with an e-mail. On Monday morning, I received an e-mail from Terese asking information such as exactly what I was looking for, how big, whether or not I could pick it up, etc and she said she'd print that out and give it to Tom and he'd see what they could do to get me what I want. Cool!

So I'm waiting on that before proceeding any further.
If that fails to lead to anything, then I will save pennies...quite a few....and purchase the slikstik cabinet. I really really like the design of that thing and the classic controller that comes with it. In fact, even if I get a cabinet from tntgame.com, I'm still tempted to get that controller.
The good thing in all this is that I didn't jump out and buy something right away. I've been patient enough that the "Hey...this is really really cool and I NEED IT NOW" has worn off enough that I'm even prepared to wait to do anything for several more months if needed.
In the meantime, I'm still enjoying visiting this site (and participating from time-to-time) , watching e-bay auctions, etc.
I've also joined "forces" with another board member and we're working on something together that I'm sure a few people will really like.
Stay Tuned....
