Hello,
I'm new here, too, and new to the concertina. I've already made my first mistake and bought a cheap Chinese 20 button Anglo from E-bay. I'll keep it to learn some scales and simple songs and upgrade to a better instrument later. I'm interested in learing some folk songs and sea shanties.
I'm finding it interesting to play compared to my 30 something years playing a diatonic harmonica.
