Is there anywhere you can buy just the rings for coop cups? Mine are bad and I would like to replace them, but the bowls are still fine. I figured I'll probably end up having to just buy all new cups with them too though, and in that case, does anyone know where I can get good quality ones that won't rust but aren't too expensive? I haven't even had these for a year 
Any help is much appreciated!
