If space isn't an issue...just get a cab.
Even a candy cab can be had for $300 or less. Shipping though, that's another thing all together.
My Neo cab cost more to ship than I paid for it, but that's part of the nature of the beast.
Buddy of mine actually has a cab that he'd probably give you if you asked nicely and didn't mind driving to Atlanta to pick it up.
Good cab:

I'm not promising you anything, but he mentioned that he wanted to get rid of it. And if you mention my name...all the better.
But really, if you can spare the space (they're not THAT big), just getting any old JAMMA cab is so very rewarding and you can play your games on that.
