What' wrong with Rico mouthpieces? I know many players that are playing Graftonite, Metalite, Reserve and Select Jazz mouthpices.A Bari Esprit Tenor mouthpiece is only around $15-17 incl. lig.... and it's a good mouthpiece, it really is.
Clark Fobes Debut also a good cheapie mouthpiece.
Yamaha 4 or 5c as Nigeld noted.
Darlene, avoid the Rico mouthpieces. Everything listed above is better.
