does anyone have a oster kitchen center food processor?

I am looking to replace my oster food processor, i have had the kitchen center for years and love it, i don't want to give it up but would like to replace the part that has given up the ghost. It is not the nut chopping/food processor part, it has 4 different blades and the hole to feed produce/cheese etc through. If anyone on has any idea of where I could find one, it would be appreciated
