My son works at a pressure washer store.He repairs ALL kinds of pw's, heated, unheated, gas, electric, big & small. He says the money is in the pump construction, and the system bypass/unloader. Generally, you get what you pay for. His favorite brand is Mi-T-M. I had never heard of it, either. They're usually superior in terms of design, material, and durability. The clincher for him is the ease of service/repair. He showed me their small portable, bought mostly by professional detailers. It was about 1-1/2' long, and about 9" square, maybe 25#'s. Built like a little brick $hithouse. I can see why the detailers like it. Maybe one of these days I'll get one for Xmas or a b-day present. Are you getting all of this, my favorite son?
