[comp.sys.ibm.pc] UPS board

I am thinking about getting an uninterruptible power supply for a PC system
and saw an ad for a plug-in card by Emerson UPS. It looks like a half-size
card with probably a battery pack taking up about half the board. One is 
supposed to plug the power-supply cables into this card which will then 
feed the whole system. It looks like a grand idea -- a UPS taking up just
one slot and not a big bulky external case (of course with more limited
charge capacity), and relatively inexpensive, lists for $249.

Has anyone used such a product before and any comments on a UPS being
a board inside a system?
