I found at sales:
Drome Racers for GC- $2
Original ps1 with one controller and crash bandicoot 2-$4
Tomy Digital Derby- $1

On anther note I got 6 various Star Trek soundtracks (Generations, TNG TV series volumes 2 & 3, TNG Encounter at Farpoint, First Contact, and Voyager) for $1.50 each, Trials and Tribble-ations vhs for $1, and 3 Star Trek books: Encounter at Farpoint, #29 Sins of Commission, and #43 A Fury Scorned for 50 cents each. For me that was a good find
