Two things I can think I'd like to see at a good con,
1st) Original Battletech Pods
2nd) Take the recreated Star Trek studio Vik did and make it portable and set it up at cons.
If I can do either one of those (or perhaps both?) on a budget of $20 or less, then you'll see that shit at VENGER CON III in Madison, WI this July...

I know battletech pods were moving around for cons a while back, they seem to be down in Houston now. The cost is high, they used to show up at cons a long time ago.
