UPSs: APC Smart-UPS 2200 or 3000?

Hello. I've been looking at getting another UPS, and I've been looking at either the 2200VA or the 3000VA units (SMT2200C and SMT3000C).

I can't see any advantages or disadvantages between either unit. Of course the 3000VA unit can handle a higher load (and needs a NEMA L5-30P socket), but that's it.

APC's UPS comparing tool shows no advantages or disadvantages, and looking at Amazon tells the same tale.

Which one would you pick and why?
 
Solution
It depends on which model 2200 and 3000. For example the 1997+ SU2200 is identical to SU3000 except max output is 1980w instead of 2700w. They even use the same 17AH batteries so runtime of the 3000 will of course be a couple minutes shorter at full load. SU3000 does also require a NEMA L5-30R receptacle (30 amp), instead of 20A because of the 80% NEC and UL 1778 derating.

1993-2008 models had a design error and send 1w through two 1/4w resistors. This was fixed in 2009.
What are you protecting and how much run-time do you need?

I personally use the APC Smart-UPS Online models. They are all double conversion units. I have purchased several on E-bay used. Replaced the batteries and you have a brand new UPS.
 
The Smart-UPS 2200, because I don't need that much run-time for a PC. Besides, it's cheaper and you'll have to replace the batteries every 5 years anyways. 6 or 7 they will outright fail on average.

BTW, You can get adapters that will fit a 15 amp socket, just never pull more than that as you will trip the breaker! If you need 20 amps, you'll want to call an electrician to get it wired up.

EDIT: If only connecting to 15 amp socket, and you run the UPS down, I'd worry it might pull more than 15 amps in order to maintain load and recharge the batteries at the same time. Best to plug them into only sockets that are rated to deliver the proper amperage.
 
Regarding the outlets: I know what I'm doing, and I know that I'll need a dedicated 20A or 30A breaker and an appropriate socket.

I also prefer to get units brand new, as I know what I'm getting. I'd rather pay $600+ more for a brand new unit with a factory warranty than get a unit off of eBay and not know what I'm getting.

FYI, I'm going to be pulling around 600W or so with a PF of about 1.
