I saw several for sale on eBay. Do a search on eBay for "Infinity Kappa 9" or "Infinity Kappa 9 Polydome". There was also someone selling a rebuild service. If you want to insure you are looking for the correct part, take the damage unit out and get the Infinity part number off the back. Search using the part number.
