Back-UPS Pro 1500VA, 2 hours of runtime at 200 watts. $179.95. Don't use the ignitor.
Not sure where you got the 2-hour figure... APC claims 33 minutes at 200 watts. See Estimated Runtime on this page to change the values:

There are two configurations of this unit one called A on the runtime graph and one called B which has another piece added to the setup. I haven't gone looking for it at this moment.
