How about Yesterday an HP laserjet 4mp for 99p on ebay with 2 toner cartridges.
I once found a LaserJet 5mpv, complete with toner, < 30000 page count, a half-ream of paper in it, and the postscript SIMM - for $15.00 at a local Goodwill thrift store; fortunately for me, it was their "half-off" special day.
I've found wonderful things there; I tend to rescue the Polaroid instant cameras that have the ultrasound ranging modules - they usually sell for $3-4.00. I've also found plenty of radio control cars there suitable for robot chassis (they're part of my "junk" box). I once found an iCybie there as well (along with a few Robosapien V1s).
