Definitely check out colleges-- (Score 1)

I was just in the halls of a community college and saw 4 seperate ads for cheap (>$250) complete systems on the bulletin boards. Most were Pentium I/II, with 8/16 MBytes RAM. The monitors were mostly SVGA, but still... one such system was only $75. Worth just taking a walk through a local school--maybe post your own "wanted" ads.
