Buy.com has the Belkin PureAV PF30 for a great price ($60). I have this unit's big brother (the PF60), and while I can't claim to hear any difference in the filtered electricity, a good quality 8 outlet surge protector usually costs a lot more than $60 (this unit originally retailed for $199).
Note: I get no kickback if you click on the link above. Consider this a public service announcement.
