If you're going to get a line, I agree with Atonal, the Vandorens are fantastic pieces off the shelf, with a good design. The other pieces I would look at are the Jody Jazz Classics, equally good, quality finish, etc.
On the other hand, I'm personally not a fan of a whole section on the same mpc. They are not a 'one size fits all' kind of thing, and what works for one does nothing for another. Are there trombone mpcs that you dont play well on but your peers love? I bet there are, and sax mpcs are the same way, with the added issue of reeds being all different.
Overall, I agree with the good Dr. G. He knows exactly what hes talking about knowing his background and what he does daily. You would be well served to have a clinician to spend time with the saxes working on tone production, air support etc.
