so, in the end, what am i buying from upsforless?:)
If your budget can squeeze it, go with my original post, AND the can of spray paint.
Else, the dark Smart 420 is an excellent choice.
The BE500 and BE550 each have the same RBC2 battery as the Smart 420, but are less sophisticated - no AVR (auto voltage regulation).
I have used every unit which I have linked, AND some of the others, and my homework was done long before this thread began.
BTW, I currently have a Smart 1400 and a Smart 1500 in service, both traditional tower models with those big RBC7 battery packs.
One unit has all of my network and phone stuff on it, and one of my computers.
The other unit has 2 other computers on it.
There are also some external USB hard drives on each, plus my screen is in there somewhere.
My runtimes exceed an hour at about one quarter load.
I wish that they would give me 2 hours though, as our average outage is 90 minutes, here in Eastern Ontario, which means that I usually am cutting it close.
