As a newcomer, I appreciate that info greatly.

Castagnari...
With the Euro at a low ebb, $2500 and a bargain compared to other one rows.
This is not a Cajun box but a one row 10 button built to a very high standard.

Most of the Quebec made boxes by veteran builders is $2500-$3500.. why?
Design, materials, workmanship of a superior quality and many make their own bellows.

Are Bon Cajuns ( Bon Temps ? ) still being made ?

To the best of my knowledge:

Bon Temps (Jude Moreau) - yes

Bon Cajun (Larry Miller) - no
