I upgraded the fence on my Delta contractor's table saw to an Incra fence. I kept the old fence/rails and cut these down to use on my band saw (same model as yours -- 14" Delta w/riser). It works perfect. Perhaps you could find someone who has upgraded their table saw fence and wants to get rid of the old one.
There are some good high quality options available, and I'm sure they would all do a great job. But that quality usually comes w/ a pretty hefty price. If you just want to cut a straight line on a board and don't mind a low tech/low price solution, try a magnetic tool holder. I use something like this on my smaller band saw when I just want a quick cut. Plop it down close to where you want it, then use light taps to fine tune it.
Now I like the Delta contractor saw fence that is repurposed and the Kreg ones are great too but right now I can easily go the magnetic route until I decide whether or not to spend some $.....A bonus I have some magnets in shop that will work..... I actually have one just like Bill suggested plus a magswitch one also that is unused at the time....All that metal base on the bandsaw and I didnt think about a magnet lol! Thanks guys!
