Cost is an unfortunate reality with ferroresonant units. In this case, the requirements of my business justified the cost, space consumption and bulk. As always, you only get your money's worth, never more. That said, I wouldn't recommend that someone get one of these beasts for home office use, even if they can afford it. In most cases, that would be too much like sending out a battleship to sink a canoe.

Above are pics of the 1.4 KVA ferroresonant UPS that sits on the floor between my desk and the wall. The second picture shows a 12 inch typesetting ruler leaning against the UPS to give an idea of its size.

The front panel of the UPS. These UPSes are "intelligent" and have a conversational command processor that can be access through a TIA-232 link. The unit also has a real-time clock so it can time-stamp log entries.
We change the battery at four year intervals, which isn't a whole lot of fun. The battery is about 25 percent larger than a large automobile battery and weighs about 90 pounds. Getting it out of or into the UPS is an exercise in avoiding getting one's fingers squished. Naturally, you have to be careful when wrenching the connections, as a direct short produces something akin to a bomb blast.
