Hi all. Great forum you have here. Just wanted to introduce myself, although I'll probably mostly lurk.
I hail from the days of the classics and used to play MAME in the late 90's. Got kind of irritated with it though, as I couldn't use classic controls. Not that I need everything to be perfect, but a typical computer joystick just wasn't cutting it. Recently noticed that it's a lot easier to build your own control panel now (thanks to you guys), not to mention that I have money to spend that I didn't then. Had the same issue with PS2s Namco Arcade Classics - made me want to play those classics even more, but was frustrating with the console controller.
So on to the questions. I'm going to start out with a prototype control panel, probably just something I'd plug into the laptop (displaying either on laptop display or to the TV.) Nothing fancy at first, probably just a couple of joysticks (robotron!) and enough buttons. I've never really been into the fighters, so three (per player) might be enough. On the other hand, given that I may end up more interested in this, should I just go ahead and purchase lots of buttons?
I'm handy enough with woodworking and electronics and computers that I don't see any issue with building, etc., and I have enough wood around that I think I'll just try out a couple of things and see what I like rather than do tons of planning for this first CP. Next question, from reading everything I think I'd be happiest with the Ultrastik 360. I think I prefer ball-top though, and Ultimarc is currently out of stock.

Anybody have any idea how long I might have to wait, or should I just go ahead with the bat top? I'll probably pick up buttons at the same time, and postpone any trackball/spinner decisions until I see how deeply I'll be getting into this hobby. Sound reasonable?
I guess that's it for now. Thanks to everybody who participates here, it's a great resource.
