I was at Sudden Impact about a year and a half ago.
I sold him a bunch of SNES stuff. If he still has a gem mint chrono trigger all complete, that was probably mine. Along with excellent Super Metroid, Vania IV, Zelda, and many others. He paid well, but it took a bit of haggling. Gave we a stupid lowball at first and I got him up to where he should be.
He was way high priced on everything, so hopefully he has come down to earth by now. Only turbo stuff he had when I was there were about a dozen "orange label" commons.
