There are several popular reels for under a $100. The bigger question is whether or not they're suited for your game, whether you'll like them or not. My suggestion would be to pick one of the highly touted, popular strings and buy a set to try for yourself. Buying a reel based soley off of someone's recommendation is not a wise habit to get into.
