I picked up a used 3" trash pump of craigslist the first of the year when I started on my pond refresh project. It's got a Honda motor, and I have to tell you it's a dandy pump. I've moved millions of gallons with it in 2015 without a hitch.

Honda motors are expensive no doubt...but they're worth it. Try to find one second hand.
