I've listed a bunch of used mouthpieces on eBay - no Mike Finns, but some good ones. Check it out:
Flash Sale: $20 off MF BT 70 Bass Trombone mouthpieces! Also works very well as a large euphonium mouthpiece. Similar in size and shape to a 1.5G, but with a slightly wider, slightly flatter rim (not too sharp) for better endurance and articulations. Click the link below to buy online.
