I have had this product for about 6 months now, and there are no ill-side effects from it, and it offers some protection for AVA and other equipment owners. It's a product by Tripp-lite called the Isobar Ultra surge protector. You can get the 4-plex for under $50 and the 6 plex for under $60 and I think it's a good value for the money.
I have used it, but they also used it at my previous place of employ (Hutchinson Technologies, Inc (HTI)), used in all of the automated manufacturing modules, to protect vary valuable PLCs, power supplies and meters. Nothing fancy, just plain old surge supression using MOVs with a latching voltage at 140 and also offers RFI/EMI filtering (at 40-80db) for a bit of treatment. I got the specifications from Tripp-lite.
Things that this unit can't do is take out lightening strikes, but will stop damaging transient voltage spikes and clean up a bit of hash noise to boot. I think it offers a value above the usual power strip as it also offers circuit isolation from components that are plugged into the same unit.
f anyone is interested in this.

I've been using Tripp-Lite Isobars for over seven years.
I have three Isobar 8's ( ISOBAR8ULTRA ) one of which has been working for me for over seven years, two of their ISOBAR6DBS and one ISOTEL4ULTRA.
I use them for my systems and my computers.
I have no illusions or delusions.
When I know I'm leaving the house for several hours or an extended period of time and I know no one will be here......I shut off all my electronics and unplug the Isobars from the wall.
I live in North Carolina and some of the houses (areas) I've lived in down here, have problems with brown outs, power outages and we sure as hell get a ton of lightning storms. So I use Isobars to protect my equipment from all that stuff. But I never expect these Isobars to be my full protection from lightning hits. Never.
I'm no scientist or electrician. I have no idea if there are any surge protectors or protectors in general that truely and fully protect equipment from those lightning hits.
I use common sense and (caution) 98% of the time. I unplug when the nasty lightning comes. And if by chance a storm hits while we're all out and I didn't have a chance to unplug because we left in a hurry (emergency or other urgent matters); I check eack each and every one of them to see if the fault LEDs.
