PrepStar 70550R Food Processor

I've had this food processor for several years now. I use it probably about once/twice a week to slice and puree. It gives consistently good results. I'm on Amazon now looking for a replacement "gate" for this, the part that stops the food from flying down the chute. I can't seem to find it here, and Hamilton Beach charges an arm and a leg for shipping a $7 part! I definitely love this appliance, though.
