Get a lower wattage, small pump and use a larger computer UPS if you need a long run time. I have a UPS with 4 batteries in in that will run my iMac and 2 monitors for like 3-4 hours, so it could run a 10-20w pump for a long time. It was about $500, if I remember right, so it was not cheap.... but nothing from EcoTech is cheap either.
You don't have to run all of your mp40s during an outage.
The air pumps with stones that come on when the power goes off are enough for most folks. If you want cheap, this is the best way to go.
