Anyone know of any good websites for looking at property for sale in California / Oregon?

In the UK there are loads of Estate Agent's websites where you can browse properties without making any commitment, but when I start looking for American Realtor sites it seems you often have to register and give them all kinds of details. We're not thinking about relocating for another 3-5 years and I just want to get an impression of what kind of property we might be able to afford!!Anyone know of any good websites for looking at property for sale in California / Oregon?
