UPS suitable for small-business network and server infrastructure

I've tried a number of UPS units for numerous small business installations, as well as my own home systems and have yet to find a reliable brand. Some units last for years, other units of the same make/model end up burning out in 2 months. Not looking for the high-end here, but what brands/models have others found that work well consistently for small scale applications?

(Small scale being 1-3 servers, router and a couple of switches)


It may be the 'pat' answer, but I've had great experience with APC products.
