The port size on the Zeros is the only thing I couldn't get past. Pi 3 is where my preference is.
Different use-cases
I want to get a few of these for UPS monitoring. Would the Zero be the best choice?
Could be a good idea, but what exactly are you planning to do? For example, I could think of a RS323-to-SNMP bridge made with a Zero or something similar for non-SNMP UPS's.
You could also use them to monitor SNMP (or RS232) and raise some alarm, maybe via SMS. There are also lots of other ARM and uC-Boards available that could do that job.

At least a Pi2/3 would be way overpowered. Do you plan to use a screen with the board? In this case, use a Zero with some very lightweight desktop (LXDE/LightDM or something similar) or use a Pi2/3.

I have lots of mid grade APC and Eaton UPS systems out there at clients. No one wants to pay an additional $200 for the network capable units. They mostly have the RJ45 to USB cord..
Raspian repos have the APC Ups software in them natively so you can apt install it.
The APC software works with most units with just a minor config file change.

Just want to get email notification. All places have wireless, so as long as the unit has that and USB, I should be good.

I'll take a look later this day, on my way to work right now. But basically what I said, RS232-to-something bridge. Shouldn't be that hard I guess. Pi Zero should do just fine, there's not much horsepower required.

Should work out of the box. Don't know the apccontrol script / software and didn't take a look yet, but it should work like on any x86 machine as long it's
a) available as arm-hf binary or
b) some script (python?) -

Ah OK, looks like there is some daemon / kernel module monitoring the RS232-port that just logs to syslog category "UPS". Next, there are two scripts that can be run in a loop or via cron which just monitor the said log and raise some action. Always great if there's something working with standards.
So you may just go ahead, buy a Zero, install the script and follow some howto, it doesn't seem to be specific to Pi or ARM in any way.

Put the WiFi dongle on your PiZero:

If I could UP vote this again I would.. I have wanted something that could do this for more than a decade. Recently with the advent of the new boards I have thought about the Pi or even the ESP8266 board.

Might want to go with the Raspberry Pi 3 then, they've got wireless built in and standard USB ports. You could plug into up to 4 UPS systems if they have more than 1 in the same area. A few more dollars, but no hassles with USB ports or wifi adapters.

Awesome. That is way better than dealing with add on stuff
@IRJ sorry to derail your thread. but I was just looking into this yesterday myself.

I agree. I was trying to use it the way that someone would use a Pi 3 as a zero client because of the super cheap price.

Really easy to use as a thin client. Zero requires much more specialty stuff.

I have been playing with the Pi for a few weeks now and I can say it is a fun toy, but the functionality is lacking.
Don't get me wrong I love playing with them and I use them daily, but there are so many common things that become a chore. Bluetooth support is flaky in different OS(es), certain Kodi add ons don't work on the Pi, etc.
The Pi does alot of good things, but it does nothing great. Although things seem to improving rapidly. Retropie and OpenElec which are the main two OS(es) I use are receiving regular updates and things are improving.
Conclusion: If you like to tinker, the Pi is hard to beat. If you want something that works out of the box with no configuration there are better choices out there. Overall I am happy since I like to tinker with technology.

Yes, it is really just a toy, don't really look to them in business.

I think my purpose of UPS monitoring is solid.
I know of nothing else aside from the manufacturer network cards that they charge way too much for.

A Pi does not replace a user's general purpose PC. Maybe in some very special cases or as a thin client.
But there are use cases where a Pi (or similar SBCs) really shines, like @JaredBusch demonstrated. I wouldn't say that it is a toy, at least it's not in the hands of someone who knows what he/she can archive with it.

So where does everyone buy their Pi from?

I've not bought one yet, but they are available from Amazon, Adafruit (pretty sure that is still via Amazon) and a few other sources.
I'd say go Amazon...
