$20 for one of the best laptops money could buy 20 years ago: is it worth it?

To any fans of old Thinkpads: I love the T530. Its the last one before they went to that heinous Mac style touchpad (so close and yet so far). I get them on ebay off lease in the $250 range. I absolutley love them, and for that price I can get one for each place I need one. I’m typing on one now from Ubuntu, but it works well with Win7 too.
