Well Johan, If I were you I would look further than the Keilwerth, which I understand (since you privately told me where you went to try out) isn't even all that cheap. True, it is a low A but I don't know how much that is going to help you if you don't play in a big band (can't remember if you do....). Basically I would go to look for something else and especially somewhere else sice on the site of that shop there are many others more interesting saxophones which appear to be sold and what's left isn't all that inspiring.
Martins and many other vintage Baritones, I understand, seem to be very peculiar about their intonation and many benefit from an accurate mouthpiece choice (as I found out with my ancient Conn stencil Bruno which I later sold) but they have no doubt the best sound around! But then again, if you loook for a solo instrument or a section one, things can be rather different. Marktplaats has, at the moment, several interesting and cheaper baritone saxophones. One is a Martin and there is also a Buescher with low A (this, says the advert, has been worked upon by the legend of the Dutch technicians Nico Bodewes )......good luck!
