I agree that APC UPSs are great, and work well with linux. I don't
buy anything else for home or work. For years though, I hadn't had
any luck getting them to work with USB (and at least at one point,
APC's own power software stated that USB didn't work with linux), so
I've always stuck with serial. Maybe when I've got some spare time
I'll give it another go.

That is not true. Many many people and companies run Linux with APC UPS

The USB APC stuff works fine for me. I just setup a brand new system with a
brand new APC USB UPS on Fedora FC4. The trick is to tell apcupsd to use
DEVICE /dev/usbhid* (usually usbhid0).

Many years ago, I bought an APC UPS that still works to this day
(though in a different role than it was originally intended for).
When I bought it, I ended up making a serial cable to connect it to my
linux box, because I was unwilling to pay APC $35-40 bucks for a
simple serial cable. Since then, I've switched out the UPS attached
to my linux box, but the same cable has continued to provide me with
timed auto-shutdown at the least. I've always used apcupsd to provide
this functionality, mostly because I've never needed anything more
complicated, so I can't confirm whether my homemade cable would
support some of the smarter features that UPSs sport today.
I can also tell you that using USB under linux, at least for any APC
UPSs, is probably a no go. If someone has evidence to the contrary,
I'd love to hear it, but even APC's own power management software
doesn't support USB under linux.
