If you have no qualms about your current laptop, why not replace the LCD? eBay the model you need and part swap. Could keep you under the 100$ range if you're lucky.
Otherwise, I'm a fan of the T series as others here have mentioned even though I no longer have one (Sister ran off with it). I purchased a Fujitsu P7010D and have yet to find something as capable in the same size package.
You didn't mention your screen size requirements so it's difficult to make a good suggestion.
