Like a lemming I've just followed the forum's standard advice and use Tripp Lite exclusively for my HT stuff. Probably overkill but so far no problems.
HT10DBS in the living room. I paid ~$80 on buy.com several years ago.
Isobar4Ultra (x2) and a OMNI1500LCD in the HT room. (I don't recall where I got the Isobar 4's but they were ~$30 and I got the UPS on eBay).
Any surge protector works. I speak from experience, my house was struck by lightning once and every single electronic device plugged into any form of surge protector, no matter how cheap, survived - well, the power supplied survived. My Ethernet network was fried, my phone lines were fried, and my CRT TVs and computer monitors were fried (from the EMP).
The $100 tripplite noise filter did no better than the $5 Walgreens brand power strip I purchase as a socket expander, not for surge protection.
****** I have thiis same console model (HT810ISOCTR) from Tripp-Lite
(information at a glance) ~ and it takes up very little space, and works fine.
Picked it up on sale for only slightly less than Parts Express is selling it for.
