Just like with cars, electric just doesn't cut it for me. Gotta go gas.
Have a Craftsman 3200 psi that I have used weekly for 2 years now, and the only maintenance is to add oil every blue moon. Bought it at Lowes for $349, runs like a top, and it was worth every penny. Went through 2 electric units in the 3 years prior. Never going back to electric. .02, fwiw.
