I just sprang for a refurb laptop from NewEgg.
It's on sale right now for $149.99, on sale until tomorrow (down from $480).
Mine was delivered last Thursday, so I've had a few days to play with it.
There is minor cosmetic damage on the exterior. Monitor and keyboard look almost brand new.
In a nutshell, everything works. Four USB ports, HDMI output, VGA output, a DVD drive. Battery holds a charge and is good for about 3 hours of moderate use. Boots up quickly, no crashes as yet.
It is a bit heavy compared to more modern laptops, but that's not an issue for me.
The system is fairly basic: Windows 7 and Google Chrome were installed, but nothing else, which is good. No bloatware that I have to spend time uninstalling.
Seller threw in a packet of Skittles.
Overall, $150 well spent. Newegg still has some in stock, but the price is up to $175. Still not bad.
