Hi RPSers!

I'm moving to South America for 9 months or so. them. I'll mostly want a laptop for music and films but it'd be great if I could play a few games, especially if I could meet up once or twice with my greatest love, DOTA 2, while I'm out there and perhaps play a few other simple 3D games. I will be travelling around a fair amount and I'm concerned about it getting lost/broken/stolen and I won't have much use for it after coming back so I want the cheapest possible laptop that will reliably run DOTA 2 on the lowest settings. I know it's scraping the barrel and may perhaps need a refurbished laptop but if this could be achieved for under 300 then that would be ideal. If adding an extra 50 would make a huge difference then I could do that.

DOTA 2's minimum specs are supposedly:

Processor: Pentium 4 3.0GHz
Memory: 1 GB for XP / 2GB for Vista
Graphics: DirectX 9 compatible video card with 128 MB, Shader model 2.0. ATI X800, NVidia 6600 or better

Any help would be super-appreciated!
