I would feel insecure with a $70 UPS. I guess our posts passed on the internet, because I just posted about laser printers causing surges. The momentary outage is not the problem, it is the surge that does the damage.
And UPSes and surge protectors do weaken with each event.

I'll second Randy's observations.
I've dealt with all three conditions at clients.

In my experience Macs tend to spontaneously re-boot for one of three
reasons.
1) There is too much current draw on the electrical circuit your Mac
is attached to. ?For example, a refrigerator cycling on, or a laser

I would not run a desktop machine without a UPS. You can get a reasonably decent one for $70 or less. When I start my laser printer I hear my UPS click, so I assume that maybe without it my Mac would lose power.
