I've never owned a pressure washer before. Between Dad and I, we could use one.
Neighbor has an electric one, he warned me to not bother with an electric one. My Dad is a retired electrician, and I can tell you that he gets a chill up his spine when water and electricity are that close together.
So... it'll be a gas powered one. The biggest project that this will see is washing my one story house.
I can get this one right now for $199. It has a Briggs vertical shaft (push mower) engine on it. It is rated at 2200 psi, and 1.9 GPM.

If I knew I'd be using one quite a bit, then I'd be looking at one with a Honda engine on it. But I'm looking at something that will be used 10 times a year at the most.
