Buying computer speakers..suggestions?

My son's birthday is tomarrow and he wants a speaker set up to go with his computer. I was just going to go down to Comp USA or CC, nothing expensive but adequate. What have you found that works for you? Thanks.
I hear the Wilsons are pretty good.
Shoe- What I use is the Altec Lansing FX6021 system, consisting of 2 speakers and a subwoofer. Incredible value and very good sound for what it is. Check this out....

Good Luck.

Thanks for all your suggestions. Ended up with the Advent system. Found it at nearly half price. My son is very happy with the set up!
