I just bought the Dell Dimension 3000 for my parents for Christmas. They use the computer for the same reasons as you, Lookout. I did upgrade to the rewriter CD drive for them also. I did some homework when looking for a new computer for them and I think that was about as good a deal as you're going to find for what you need it for.
Oh, and there's plenty of
free pop up stoppers out there for the taking!
