You know, I may continue my search for one, but I'm certainly starting to consider just getting the bastard down and dipping it in plastidip. I saw a post on lifehacker a few weeks back about folks using it on their frayed headphones, worth a shot either way. Do a couple coats get it sealed back on the top and just get a new mast.
Thanks for all the info everyone. I'm gonna try those searches on ebay. I'm thinking at 1/5 the price I'm certainly open to modifying one of those before spending tons of cash on OEM.
Thanks again everyone. Always a quick and useful response from the fam.
