my own playing is probably in the clapped out Crosio bracket too, but as an instrument maker by profession I need to support the hypothesis that a new instrument will make you a better player.....

... even if I don't believe it. ( My current stable includes the 1931 Cooperativa Armoniche three voice musette with Basson, ditto a 1949 and 1951 Buzzi Frères, a 122 year old Concertina and a second one seven years short of the century... .)
So far I have baulked at spending that much on any instrument even though I expect my customers to do so.
Geoff,
As you have mentioned previously, there are loads of older unwanted CBAs in France, so who is buying new?
Most French shops now offer the Hohner Nova as the beginners' choice, so Maugein and Cava must be losing out on new sales. I can remember the day when beginners were all urged to buy those very pricey student models offered by the big makers, on the basis that they could always be traded in for bigger instruments when the student was ready.
Don't know how many new boxes the big two are currently turning over in a year, maybe a tenth of what they were doing 25 years ago?
As an instrument maker you must be able to see the difference between what was and what is, and I suppose if buyers even wish to get anything approaching the quality of old then they need to dig deep.
If I can remember correctly what I was earning in 1980s, that brand new Cavagnolo accordion probably represented about 6 months mortgage payments, so it seems that new accordions were actually considerably cheaper then. The same model is now €8000, so that would probably equate to at least 12 months' average UK mortgage payments in today's "money".
That said, it is obvious that construction costs and materials have escalated considerably in recent years, and companies like Hohner will be cashing it in.
When I committed to buy that new Cavagnolo I almost baulked at the price, as I had a big mortgage and a very young family. These days I wouldn't even have been able to consider it. Did it make me a better player? Well, considering I found out years later that row 4 was 3mm too close to row 3, I always did wonder why it was such a b*****d to play!
I hope your order books are full, as pros will always seek out the best, regardless!
