seeking recommendation: UPS for Freebsd

Hello:
	I have an older APC UPS (BackUPS RS 1500) that after years of
excellent service _may_ need to be replaced.
	Is there a particular brand - or even model - that folks would
recommend for a medium-to-heavy home office environment?  (This isn't
the only UPS; it's just the only one causiong problems right now.)
	Budget is not unlimited, so I'm not looking for anything fancy;
just something that will (with replacement batteries) just do its job
for the next 15+ years.
	And - of course - works with software running on FreeGSD.  (I use
apcupsd, and have seen nut used elsewhere.)


			Respectfully,
