I'm not at home to check right now, but I think I got a Johnson 500gph bilge pump from BassPro, and whatever cheap float switch that was next to it in the store. I think it was 24VDC, but I could be wrong about that. I just added an AC/DC adapter I had lying around so I could plug it in.
I never considered the possibility of corrosion buildup on the float switch that PhysicsDude referred to. It was a cheap part, so that could be a concern. It's been going strong for about a year+, though, and it always sits in an inch or so of water. No problems thus far, but maybe I should inspect it to make sure all is well.
I have the output running about 10 feet in length and 3-4 feet up, and it has more than enough power for that.
Total cost was somewhere between $35-$45
