I ended up getting one here locally for $225, apparently a Falcon chipset.
Came with 10 original games, so I tool the crap ones to Gamestop and traded out for a spare controller.
Works fine, stays cool (I leave it plenty of room to breathe just in case!)
and plays anything I throw at it as long as I patch it if needed.
Hopefully I'll get some mileage out of this one.
Gonna try GTA Liberty City Stories, time get get busy slappin up some ho's!

Thanks again, ARCADIAC!
