The last 3 PCs I've bought, I've bought directly from Dell. I have no complaints about any of the machines, and Dell replaced the display on my wife's laptop like a week after the warranty expired w/o any problem.
My XPS desktop is finally dying after 3+ years, but I bet if I just got more RAM, it'd be back in business. The Inspiron 1720 I currently spend all my time on runs beautifully.
