Martin committee is a good choice or a conn 6m. Most vintage horns are good for jazz, just listen to the old recordings Dave

Vintage Conns are great for Jazz, Both the late chu's and 6M's could be found for a decent price, and have a nice broad jazzy sound. The mouthpeice will have a large impact on how it functions for jazz.

The best vintage saxes for jazz are(drum roll and cymbal crash) The Martin Committee, and later The Martin models(Art Pepper) Conn NewWonder(also known as the Chu Berry model) 6M, 26M Connqueror Buescher Aristocrat(just listen to Johnny Hodges to hear that horn) 400 Top Hat & Cane King Zephyr and Super 20(Charlie Parker and Cannonball Adderley) Selmer Balanced Action, Super Balanced Action and Mark VI (Overpriced IMHO) For $1500 you should be able to find a good vinatge horn. Check the reputable vintage sax web sites. This one, and vintagesax.com, junkdude.com, worldwidesax.com, are among the better ones. Personally, I highly recommend Martin Committee models, because they are simply awesome sounding horns. Try this web site for information about Martin saxophones. www.themartinstory.net It gives alot of information about all of The Martin models, with photos. The best of them are the saxophones with The Martin Alto on the bell. Beautiful looking, killer tone, and better ergonomics than other vintage horns aside from Selmer and King Super 20.
