Which budget laptop?

Hello people of tom's hardware,

I am needing a laptop for college school work (pre-pharmacy @ UofA, so no intensive programs will need to be run on this laptop) but I would also like it to do some light and casual gaming. i.e. Baldurs Gate II, Neverwinter Nights II, WoW. I don't own these games, except wow (haven't played for a year, but i may get back on), and they look interesting enough that i would like to play them with my brother online. I am assuming since they are older just about anything will run them. I would really like to play some of torchlight II and Diablo III on this thing if possible. Lower settings are ok, low FR and lagging are not.

I am not sure how unrealistic my expectations are since this is a budget machine and my wife will let me spend ~$400 +/-$50. I have picked out a few deals going on and would appreciate any input between the 3, or any suggestions outside the box would be great as well.
