One model's pressure might take the paint off your car, another might barely take the crap off last nights dishes. I'd aim for at least 100 psi. The gallons per minute doesn't really matter, it just means it uses less water, and the lower water consumption ones are usually far superior (and more costly).

Electric pressure washers will never hold up in a commercial environment. I doubt if you can find a pressure washer that only does 100 psi, that's absurdly low, you can do better than that with an air compressor or by squeezing your thumb over the end of an ordinary garden hose. The higher psi and the higher gpm usually indicates a better machine, not the opposite.
Costco and Sam's usually do have some of the best deals on pressure washers. Honda engines are famous for being reliable, the only problem is that you pay a premium for that reliability, which might be worth it for commercial uses, but if you're on a budget they might be too expensive.
I think that you'd probably want to be in the 2500 to 3500 psi range, that's going to be more important than the gpm, but maybe the 2 to 3 gpm range. Those sizes might be a little over your budget is the only problem, but I think that you'll see end up wanting one about that size in the long run, rather than a smaller one. They're still fairly small units, but they should be good for most things that you need them for. You will find other uses for one once you have it, so you really don't want it to be too small to handle a lot of the other things that you want done. Also look for one with a variety of tips included, which most will have. You don't want to be using a tip that bends the fins on the ac units.
