What do you use for <5kVA UPSs?

I was just wondering what some people are using for small (<5kVA) UPSs that are left in unmanned locations running critical network equipment (so management and monitoring are also critical). I'm curious about units in the 2, 3 and 5kVA ballparks since different solutions will be needed for these two different capacities. What vendors support 20A 120VAC outlets on their products? How reliable have your units been? Any comments on SNMP management? Thanks in advance, -- Craig A.
