I have posted recommendations on this forum for Toontrack EZdrummer, the program which has 'saved' my life in terms of song-writing.
I actually paid full price for the EZdrummer Jazz Expansion. Since then I have have signed up to Toontrack's mailing list and found out about this deal: Half off any drum expansion.
You need to have the actual EZdrummer program, but then you can get the Jazz expansion for just $40. I swear by it. Here is the link while the promotion lasts:

If you want to hear what the Jazz expansion sounds like, either go to Toontrack's website and listen to demos...or even check out my music page(I only use this expansion on the 'jazzy' songs, NOT the harder rock tracks)

If you are considering doing this, feel free to PM me any questions.
You can for example: Export MIDI drum file from Band in a Box, and then load in your sequencer to play the Jazz expansion.
Also...For jazz, I am guessing there are only four expansions you would consider.
1) Jazz expansion
2) funkmasters (to do that Herbie Hancock kind of stuff)
3) Latin drums (if you want to throw in congas for that Ray Barretto feel)
4) Classic drums (can be jazzy, but this latest expansion is great for fusion, classic rock, blues, etc)
I hope people catch on to this!
