I am very happy with my Morse Anglo. I can't really compare it with other anglos apart from the Hohner which I started out with and it is definitely very much better than that. Not to knock the Hohner it did its job and got me started.

A number of people have commented favourably on the tone of the Morse including a friend who has a Wheatsone so it seems it is a pretty good instrument even if it does have accordion reeds.

I suspect the difference in price between the mid priced hybrids and the high end instruments lies mainly in the reeds. Accordion reeds are mass produced so good quality reeds are available at a reasonable price. New concertina reeds are largely hand made so come out much more expensive.
