It's not flagged as discontinued on the APC site, though it seems to
have been dropped from the RATS page. Maybe in the process of being
discontinued?

Ugh, of course I come across something (TwinSource DCC-II RM-ITSTS, 50A
in a 4U case using SCRs) mere minutes after posting. Any other
recommendations are still welcome. The TwinSource unit looks quite
fascinating, although I'm guessing quite expensive.

The main downside to the SU045 product line seems to be a lack of network
manageability. Doesn't mean you can't get 'em. 
APC doesn't make RATS units larger than 30A, though, so if you need a
50A unit, you'll have to look elsewhere.
