I would say that what you really want is a Line Conditioner, of the  
sort the sell for use with sensitive Audio/Video equipment. That  
should get the power output into good enough shape for any equipment  
you might connect.

Failing that, most UPSes I know of are pretty good at being able to  
take in bad quality power and output something that is at least  
minimally acceptable for most computers. Your primary risk here is  
burning out the UPS, if the input quality is bad enough.
