If you are talking about the machine at Sam's Club I wouldn't go with that one. That machine they sell there, just like at Home Depot, is a direct drive unit. I would go with a belt drive unit. Belt drive is all around much better then direct drive. I know that Mark at Easy Clean Systems had a 4 gpm 3500 psi machine for sale for the same price awhile back. He runs that sale ever so often. You should call him and see if he could help you. His # is 1-800-292-3279. You don't need the extra 500 psi. I hardly ever use above 2000 psi. What you want to pay attention to is the (gpm) gallons per minute. The higher the gpm the better. If you could afford it I would say go with 5 gpm or higher. Whatever you do though don't go below 4 gpm.
