Before you all jump up onto the phone and send me a UPS, I would be interested in getting hold of the circuit diagram for such a APC unit. That way I can make it up myself over time and save a fortune.

Do a Google search on home made UPS systems. Deep cycle marine battery(ies), voltage regulator and charging circuitry are the main ingredients. If you take basic safety precautions and get help where you aren't certain of what to do you can build your own UPS system for a reasonable price. Especially since you can buy the batteries at reasonable prices. An example: http://www.markbrown.com/ups.html is an example of a high-end/high-$ setup. Stan
