:) I'm beginning to resemble that remark myself. Thats another albeit probably higher priced solution, but it wouldn't take a 1500 W rated ups either, smallest would do fine I'd think. 15 seconds of holdup to a 20 watt load should be more than adequate. I hadn't thought of it but I'll check that out too. Found a 650W at tigerdirect, factory refurb, $35.30 w/tax.
