From all of my experience, the EX will work for jazz. The horn is nice and heavy and gives a dark tone. With the stock mouthpiece, (similar to a C* but more open internally) It provides a very palatable and flexible sound in regards to tone and pitch. It is very easy to play as you. For 2000$, it is a very good deal provided that the horn works. Mine was also around that price, it was an old store demo model. Be cautious but this deal sounds like you could walk away with a great horn. Be sure to do your research.
