I have been playing McNeela Wren for a couple of years and it is no longer working for me. Slow action, sticking valves and leaking. I am ready to upgrade and trying to decide between three concertinas. I lean toward purchase from Concertina Connection since I am located in the Northwest, as they are. I am too far away to travel and try different concertina. I want an Anglo C/G. Does anyone have experience with the Minstrel, the Minstrel with Wakker bellows, and the Clover?
