Use Golfnow. It's just about the only way you'll get around the "non resident" rates. Courses that charge locals $50 will want $125 from tourists. If you get a Golfnow Hot Deal it doesn't matter. Golfnow owns the Hot Deal tee time and they don't care who they sell it to.
I never paid more than $50 and often lots less. One day we paid $35 and the two guys we played with paid over $100, I think it was $135.
If you have a car , make the drive to Mesquite and play Wolf Creek. It's expensive but incredible!
