I've got a $400 Troybuilt XP w 2600 PSI and 5 tips. It was purchased about 6 years ago when my electric unit died. The good part is that the Honda motor ALWAYS starts easily. The bad part is that it's a PITA to store and move around. It's also a PITA to set up for use The plastic on the frame and soap bottles is cheezy and breaks easily. Lastly, they had pump problems with these. Run the motor with no water attached and you have a $400 piece of junk. The garden hose kinked on mine once so the pump slips now and then.
I bought it back in the day where I needed to reach up two stories to clean. It did that marginally. Now I own a ranch house and could get by with allot less. In fact, if this died tomorrow, I think i'd just opt for a smaller ( but quality) 1600 psi electric unit again. Like most people, I overestimated my needs and the capabilities of the machine. ( i.e 2600 PSI can destroy siding/decking FAST if you have the wrong tip installed. (I learned the hard way that for most jobs, less pressure is better than too much.)
