You can search for real estate in and arround the Corvallis area at:
Which is a website that receives 2 mls feeds on a daily basis that covers a majority of the Interstate 5 corridor. We are plugging in the WVMLS data soon at which point we will have Oregon covered by majority, save central Oregon markets that have MLS's which are not quite up to speed.
On HouseNow.com we have market data for Corvallis, Albany, Lebanon, Salem, Junction City, Eugene, and in between. We use interactive mapping (compliments of Google) and are very excited in how our site compared to others. You'll find it useful, so enjoy.
