I have a Powerwash 1350 PSI, that I got on sale from Home Depot. It might not match up with a Northern or that sort of thing, but for 70 bucks, I'm not gonna cry when it goes out on me. It only gets used for about 5 minutes per car (rims, wells, mats, some trim), so it should last me atleast a year or so. There are much better electrics out there, but the good ones start at 500+ bucks, and I just dont use one enough to justify it.
