well it depends. On alto people usually try to stay away from metal pieces b/c they usual sound bad on alto. Sonny stitt is an exception. For alto, under 100$ hard rubber Meyers are good, also rubber otto links are good for jazz. For tenor, it depends, metal otto links and rubber otto links are good. Morgan mouthpieces are good. the most economic ones are the links i think. the BARI hard rubber pieces can sound good with some work.overall the best moutpieces are gonna cost you, but you can sound like coltrane or rollins on a stock link.
