I presume you are talking about metal bats. If so I'm a big fan of the Louisville Omaha. Their top of the line exo-grid is ridiculously expensive and their next in line, the Dynasty is pretty pricey too.
While not "cheap" the Omaha is a pretty decent deal and I always find it interesting that at schools sponsored by Louisville the players typically chose the Omaha even with any other model available. I take that as a pretty strong endorsement.
