What is the best laptop Dell sells for its price?

I am looking for a portable (i'll beusing it for school), large hard drive 250gb+, and not too large so in between the 4.5-6.5 lb range. Oh and by the way it has to be a Dell.What is the best laptop Dell sells for its price?The Inspiron 15 that starts at $599 (the one that starts at $399 is a crappy Celron).
