Your main worry is/should/will be power surges unless you've got something like projectors which need to cool down and that's another ball-game. Save yourself some time and a lot $$$. I've advised fellow AVers many times to consider per below. I do not post here often but here's the basics:
a) Goto eBay and search for "SurgeX sx-1120-rt" or "SX-1115-RT".
b) The "RT" is important b/c it has
all the features: COVUS, ICE, SurgeX, Over/Under.. and then review the seller's feedback. Only buy from those with good, solid feedback, look at all the photos carefully and watch the S/H as it can be $50.00 for these units due to the box size and distance. I also recommend people do not buy the ones where someone cut off the 20A male plug and replaced it b/c they have a 15A outlet. If you do that, be sure you check their wiring. I've seen some real shady stuff done recently in 1 unit I picked up for parts. Not pretty and it was clearly done by someone not well trained.
c) You should be able to get one of these in good condition for $100-$200 delivered if you are
patient. I see several listed right now in that range.
d) Sometimes they might have scratches or the ears might be dented... but that's mostly cosmetic and nothing that bothers me as long as the internals are fine.
e) If you get a 20A (SX1120-RT) one, then you will need a 15A -> 20A plug converter to plug it into your power outlet unless you have a 20A outlet (doubtful) for AV setup. (NEMA 5-20P plug
(requires a 20-amp circuit and a 5-20R T slot receptacle) Those cables are readily available.
f) Worse case you need the 7-pin
phoenix connector on the rear to bridge 2 pins which allows it to switch on the "switched outlets." Those are from mouser easy. When you look at the rear, you can see if the 7-pin molex is present or not.
g) Another option is to use the SurgeX "SX2120-SEQ" which is the same thing only it does power sequencing across 3 banks. This is very useful for controlling in-rush across multiple high-powered amps. The simple 12V triggers from many AV receivers and pre-amps can trigger the SEQ. I saw those going for $150-$250 recently too in very good condition. These come in 2U and 1U formats. Don't see the 1U often and when they appear, they are usually more $ than the 2U units so if space is not a concern, go for the 2U.
Also, we've talked about this many times on AVS so here's a link to the last time I helped someone else with similar questions. I think he got a unit for $50, added the phoenix connector and he was GTG and very pleased.

I also like Furman's "SMP" products as they deploy a similar (but not the same) tech and those you can find usually at reasonable prices too and they are well made.
YMMV. The "series mode surge protection" is some of the best at doing the job well on the market.
Stay safe, stay alive.
