This is the same advice I give. No-one can tell you what system is right for you, though many will try. Try the Clubs and Organisations section of my own site www.concertina.info for links to groups all over the world.

It's also worht remembering that cheap concertinas don't keep their value, but more expensive ones do, and may even gain. They can work out cheaper in the long run.
