I bought Lenovo 11e chromebook for $24 with free delivery on ebay. Disassembled the unit and unscrewed write protection screw, installed new BIOS and GalliumOS. Works pretty OK'ish. I use it to watch videos: youtube and video services I need (movies online) work well. Battery is pretty good as well.

There is no magic though. You get what you pay for - I can't do modern JavaScript development on it.
