I get two pumps running and we're inflated in no time.
Ditto, my Coleman has lasted for two year's worth of trips. No problem filling two or three boats per trip and I bought it on Amazon for $16. It takes care of the bulk of the filling then leave me to top off by hand. The electric is not much faster than pumping by hand with my 4" pump, but it is a lot easier. I have a K100 for topping off each morning and I love how easy it stores since there are no hoses to deal with. If you go on the cheap you can pick up a backbreaker pump for $25 or so as a top off pump as well.
