I purchased a Troy Built model from Lowes about a year ago. It has a gasoline engine and produces 2 gpm/2350 psi, I am more than happy with it. One thing that I currently am wanting is a bendable wand. The one provided is stainless but has no flex, thus a person has to lower the wand angle (i.e. scrape your knuckles on the concrete) if using to effectively blast the upper wheel wells. Simply my observation!!
