Both of ours were referred to us by friends who had actually used the realtor in the home-buying process, and that worked well for us.
The first thing I'd do is point out to the realtor that you want to see listings for all homes in your price range, or all homes that meet certain criteria. Our first realtor started only showing us homes that were in a $10,000 band of price ranges until we said that we'd like to at least see the listings for ones that were priced lower. If an attempt at communicating exactly what you want from the realtor doesn't work, I'd find another. (And I'd tell my aunt why. The realtor may be a great friend, but a poor realtor, or a realtor whose real interests are a different type of business than what you are giving her.)
