Hey gang, Just FYI -- I picked up the Ant Commandos adapter ($20 from Amazon) and it works perfectly. It lets you use a PS2 Guitar Hero guitar to play the PS3 versions of both GH3 and Rock Band on the PS3 (and the PS2 version of GH1, but not GH2 or GH: '80s for some reason). It also works as a plain ol' adapter for using PS2 controllers on a PS3. I was able to use my PS2 GH1 guitar to play PS2 GH1 and PS3 Rock Band on my 60 GB PS3, no problem. Although to play the PS2 game I had to change the controller number of my remote control from #1 in order to get the game to recognize the guitar as controller #1. As far as gameplay goes, everything is great. The old GH guitar BLOWS AWAY the official Rock Band guitar. Sadly, the controller # LEDs on the adapter don't appear to work (the connection LED does), but I don't care enough about that to bother sending it back for replacement.
