I have a 30 button Anglo made by the same people. It actually looks good; the wood is nicely finished. The bellows are quite airtight. The action is similar to an old Stagi - each 5 buttons pivoting off a single thin rod. Mine has plastic valves, which is supposedly an improvement over leather valves on other cheap instruments. The straps are definitely cheaper and worse than the ones on the Rochelle, but they work and are usable. All the buttons work and are in tune with each other. The buttons don't always stay straight coming out, as the sides are their guide. I don't think this is an issue with the Rochelle/Jackie line, as they have a riveted action. The buttons aren't so bad that they stick or go all the way in, so this hasn't been a real issue. While I don't imagine that this concertina would last through prolonged use by a serious player. it has served me well as a learning instrument. Percentage wise, I stand to lose quite a bit on resale, although this is unimportant as the actual dollar amount I stand to lose will be relatively small. Mine was $170 including a pretty nice case. If I had it over, I probably would have bought the Rochelle, which was $285 and readily available at the time, because of the trade-up policies available from sellers.
