I was just about to rent my clarinet at £60 for 3 months but now I've seen a lot of Buffet B12s for sale on ebay at approx one third of new retail cost. They are used but hardly at all, so they say. Can a clarinet expert please help with the following queries?
Potential buyers are asking for serial nos. - Why is this?
What about the hygiene factor of using a used mouthpiece?
Are there any disadvantages to buying one off E-Bay?
