FWIW, David R Foley (It's A GoogleTrap!) is a member here, so hopefully will chime in. He definitely won't want me involved as I've been less than kind in regards to my characterizations of him, but he has made some pretty cool stuff and I do hope to buy one of these at some point.
I would like to see a review by someone like GameRoom Magazine or RetroBlast. Alternatively, if it were to be someone here, I would vote for someone like u_rebelscum, Tiger-Heli, etc.
Someone at Happ was testing the board and there was some issue, which I understand Nanotech was looking into (I think it was something simple like a wiring harness).
For those of you using LCDs, they also are working on a sonic version of the board (works with sensors).
Sorry ... I'm too lazy to look for the appropriate threads right now -- guests are arriving and I am getting dirty looks from Mrs. Cheffo for having my notebook on the counter while cooking.
