Lot's of X-arcade haters I see....
hehe
that's cool, to each his own...
As for me, I enjoy the X-Arcade. I've had mine since they first came out, actually pre-ordered it.
Since then, I have logged many an hour on that cp....it has taken a beating, and never given me any problems.
I do however agree, that the controls are a little too close together, but it's for sure playable....
When I finally got around to completing my own cabinet , I made the decision to run 95% of my stuff off of my Xbox and PS2, AND use a TV as the monitor. You can say what you want, as far as I'm concerned, there is no easier way to accomplish that, than to just use an X-arcade.
Sure, eventually I may take my X-arcade apart, and re-use the hardware in my own custom built CP, but until then, the X-arcade is a quick, easy, inexpensive solution and IMO should not be totally ruled out.
(PS - on the fact that they are 8-way and makes 4-way play difficult, they offer (for free) small 4-way adapters that you plug right in to the joystick, and they work very effectively.)
