Buy one that you like, can be a bad one, good one or anything. As long as it meets the recommended requirements for the game.

If you buy an old one, just upgrade the RAM in it, or whatever needs to be upgraded.

I got one for $600 and it runs WoW Great.|

Its a Toshiba Satellite A205

We got my dad a laptop for his birthday and my computer crashed (and totally wrecked) so i d/l ed it on his laptop (it was a crappy Acer Aspire 1250 only for $450) and it worked fine.

buy new,……… not 2nd hand, as repair jobs will make your money disappear faster than a jack rabbit.

500 to 700 dollars Check out walmart they have some pretty good deals there name brand one my friend recently bought his for 680 some where around there with a pretty big flat screen monitor its HP and 3gb which is perfect for running world of warcraft but its a desktop but don’t be discorage they also carry laptop as well that are really amazing and the prices are amazing i would suggest getting something that has 3gb and the memory not so much important because now a days most computer come with at least 250gb memory more then you’ll ever need.

You should get an apple.
