I'm still a fan of the Tsunami AT-1. It's worked perfectly for 7 years with absolutely zero maintenance. It uses a change in air pressure to turn on a powerhead in a Brute can reservoir. Should be able to find one for $50-$60.

Another float valve that can be used is a Little Giant float valve from Princess Auto (UFA probably has them as well for water troughs.) They cost somewhere around $6. You should remove the brass hinge pin and replace it with an acrylic rod. Mine worked without cleaning or maintenance for years without fail until I sold the sump. I believe I also removed the water line fitting and installed a 1/4" hose John Guest style connection (that's another $2.60

I've used one of the little giant floats for years in the horse pasture, hasn't failed yet. It's just bolted to the trough, unprotected from the animals. They work well is what I'm saying. I'm sure I got mine at UFA that's about the only place around here to buy stuff like that. Gallagher also makes a similar float, I have no experience with it though.
