What do you want it for? Constant use? Occasional use? How much pressure you need?
Of yuo are going to do some light cleaning once or twice a year, save some money and get a cheapo electric for$75. Throw it away and but another after 5 years.
if you
really need a big, powerful, expensive unit then go for a more expensive one.
BTW harbor freight has several that start at 2000 psi and 4 hp for $270 and go up to 2500 psi and 6.5 hp for $350.
