First question: Anyone have a Monette B4 they wanna sell or part with (or know of anyone who does)? It seems nobody has them in stock right now, and I'd rather not wait if I didn't have to (I know, not very patient). Second question: I keep seeing these Kanstul "replica" mouthpieces that are supposedly exact copies of Monette pieces. Are these actually a true copy or not? I would think that even if they exactly identical, that you'd still have differences due to the type of metal/alloy used, weight, etc... Thoughts?
