Yeah, got my eye on ebay.

Ive contacted a couple sellers with what appear to be homemade product.

Problem is my outside diameter is an odd size I suppose roughly 1.875" finding an inside diameter a hair smaller or spot on is tough so far. The wall thickness of the TB lip is only 1/8", so not alotta room to play with. That and I dont really have a means to trim the lip down consistantly all the way around. But Ill see, maybe on of them will make one a little smaller for me and keep their nice low pricing. \:\)
