I can only speak of my own experiences, but mine works great. Uses Neo-Geo controllers, which I already had. You can buy their power supply or just use your own. It's RGB-only, so 95% of what it's doing is just pass-though. Build quality seems just fine. I think the quality of the power supply is more important, frankly. This uses a standard molex or whatever connector so you could just as easily use a nice PC power supply with it, I think.
