The one I use is a 1500va apc... http://www.cdw.com/shop/products/default.aspx?EDC=496788 and is $189.38 from CDW. You may be able to find it cheaper. Honestly, it depends on what you want to do with it. If you just need it to keep power going until you can shut things down, you don't need something huge. If you want it to finish the job and then shut down... You may want something with a little more power for your situation which is one more head than I own. Still, 2 of the one I have is only $400. I have one amaya and one computer hooked up. It's held up and kept normal jobs running till the end. In our area (a new development), power would go up and down a few times a week. My monitor and everything else non essential are hooked up to the plug that filters the power only, but doesn't keep it on in the event of an outage. CRT monitors a HUGE power hogs. APC has a bunch for less that are in the 2000 - 3000 va range for less than $700. Anyway, good luck with your purchase! :-----Original Message----- :From: amayausers-bounce@xxxxxxxxxxxxx :[mailto:amayausers-bounce@xxxxxxxxxxxxx] On Behalf Of Mike Garber :Sent: Monday, March 28, 2005 10:54 AM :To: amayausers list :Subject: [amayausers] Battery Back Up : :Does anyone have any advice on battery backups? :A 1500 watt APC to cover 2 Amaya's and one computer is $699 (ouch!). :Do I even need one?
