When it comes to pressure washers the most important part is obviously the motor, get something with a good brand name like Briggs & Stratton. Electric PW's are just toy's, stay away from them. Get more power than you think you will need, you can always dial down the pressure, better to run one at 3/4 power and have a little extra if you need it than run one full out and not have enough jam. Ask anyone that has one if they wished theirs had more blasting power, chances are high that they did wished it did. A lot of the ones for sale are just toys, barely more blasting power than a garden hose with a thumb over the nozzle.
The one I got can peel paint with ease. It's downright dangerous at full power. I run it at about half gas and has all the blasting power I need and I'm not running it very hard. In this case, bigger is definitely better.
This is the one..

Has a Kohler 6.5 HP on it. It's an AWESOME pressure washer, I HIGHLY recommend it. Had it for a good 5 yrs now and has a TON of use on it and it's never givin me problems. You won't be disappointed with one of these.
Shop around, found mine on clearance (can't recall where) and got it for a shade under $500
