I'm going to add to the bandwagon slightly. There really isn't anything in the $20-$25 range you are likely to enjoy as much. HOWEVER, at $40-$45 you can find a recent vintage of Chappellet Signature. That you might enjoy more than the Caymus. Lewelling can be a fun, easy CA Cab when young. Those should be $45-$50.
In your price range I seem to recall people enjoying Chateau Ste Michelle Cabernet Canoe Ridge, but its been a while. Also, Sequoia Grove Cabernet can be quite pleasant. But neither of these are going to be at the quality you are looking for.
