From what I have heard the cheaper electric units are Ok but dont last very long.
FWIW, wife gave me an Excell 2500 PSI from Home Depot and it was "cheap" (plastic hose, cheap wand, etc...)
I returned it and kicked in a few extra dollars to step up to a 2600PSI Honda unit...The thing rocks...I use it on wheels, tires, the garage, driveway, pool deck and it is a plaeasure to use.
You may want to spend a couple of extra bucks now and get a good one that will last you
