Haven't tried the new boards, but I hear they work great. If you can't find originals, it's definitely worth the investment. How much do you want to put into the machine?? I would think that you could do some really cool LED effects with the mirrored backglass on Xenon. I'm trying to remember, but I don't know if the sound in the game would benefit from a subwoofer (don't think so).
Xenon is a machine I'd like to have one day.
