TTIs Vs. Doug's
An update - Actually found the doug's for $650 coated!! They should be shipped straight from Doug's tomorrow. yeah!!
From my previous experience this is a really good price. Here is the website. They only have the non-coated versions listed, but if you call they can order the coated.
