Sorry for the late reply. Thank you guys for all the help. I think I'm settled on Acer Aspire 5742g/5750g/5755g as long as I can get one with an i5 processor and a GT 540M/HD Radeon 5650. They don't seem to be bad. I just hope the local prices aren't more expensive than the prices I checked online.
On a side off-topic question, I bought a new 1 GB Ram stick for my laptop, how do I check it to make sure it's free of any errors?
