Tom, I bought the next size up p-washer from Northern a couple years ago: I believe 9 HP, 3250 PSI, 4 gpm. I thing it is a well put together machine. I bought it with the CAT pump and I would do it again - I think it is one of those things worth spending a little more to get the best. After all, a preassure washer without a pump is just a motor :) I like the idea suggested about buying a pump separately and rigging it with an electric motor. One item I am accumulating too many of is small gas engines that need to be maintained. I wouldn't worry about having too much preassure - If you are washing something that concerns you, put a 45 degree nozzel on it and don't hold it too close. Having said all that, I am a not the biggest fan of preassure washers. They do great on thick build ups, and porus or irregular surfaces, but are not very good for washing cars, trucks and , campers etc. Basically, you need to hold the nozzel within about 4 inches of the vehicle to get it clean with no obvious residue. At that point it is quicker and more effective to use a brush on a handle or a sponge. As for hot water machines, people say they are much better and I would not doubt it, I have not experience myself. Note that you can run hot water through most pumps, up to about 140 degrees F or so. You could hook a regular machine up to domestic hot water and achieve the same. I have not tried this with mine yet, but may soon. Good luck. Tim
