I recently picked up 2 Grid 1450sx laptops, 2 LCD-286 "portable" computers, and 1 Packard Bell 38625nb4mi120-base laptop.
Got all of these for $150 on craigslist... the seller threw in an HP iPaq 5455 Pocket PC when I went to pick these up.
So a total of 6 computers... sadly these Grid laptops have no power supplies.
All of these computers (except the HP Pocket PC) have mechanical keyboards, and the Grid laptops are my favorites (so smooth) by far.
I plan on recording some videos about these later on, once I get them up and running.
