Ok, so having seen what can be done with one on YouTube I have decided to go have a look at a Rochelle this Wednesday. The deciding factor was the five fold bellows on a cheap lachenal, not good since I want to engage my inner Peter Bellamy and learn some of his material. Being a non player at the moment what checks should I make to be sure I get a good un. Also, is it worth trying more than one of the same model in case there is a variation in bellows quality? Thanks.
