Hello, I'm looking for a concertina for my daughter. I think she would have fun with a concertina and am trying to order one for Christmas. I am probably looking for something I can order from the US so I can receive it in time. From my research, it appears we need an Anglo, and I think 30 button would be better to give her more options. I had been looking at a Wren from McNeel, but it looks like I can only get one from Ireland. So I'm down to the Rochelle and Rochelle 2. Are there more I should consider? I do not want to exceed $600.
