Karen,
I just looked up the price for a replacement for this part. US$2,269 is absolutely insane! I could make them out of 316 Stainless Steel for way less than that. I have to remove mine this winter for cleaning so I may just design a replacement and put a few extra on the shelf. Unfortunately, that will too late to help you guys out.
