What is the average time for a UPS to switch from line power to battery? I now there are some more expensive "inline" UPS which don't have a switching transient, but I want to see if I can use a less expensive unit.

Depends on the type of UPS. From Electropaedia:
In my office, we have several of the ES style APC UPS's. Our building has a diesel-powered generator that comes on within 1-2 seconds after a power loss, and we use these UPS's to cover the period between power loss and the generator turning on. I've gone through their documentation for these models and I can't figure out what type they are. I also use these same UPS's at home and my computers have stayed on during a power loss.
