If you can stretch the budget to $129 or so... you should be able to get a pair of Edirol MA-10Ds - I've used them as micro monitors, and use their big brothers the 20Ds as desktop monitors on all but one computer.

They're clearer than you'll get out of "multimedia" speakers... you won't get the crappy rattly plastic bass you'd get out of $100 Altec-Lansings, but really, who wants that anyway?
