I just called a shop about this today. They quoted me $2700. Price has gone down but still expensive. He gave me a idea though. A hybrid. It's a Vorsteiner lip with the ACS hinges. I first I was reluctant but he showed me a picture of someone who did it and it looked great. So I'm going that route.
And again, I apologize for bringing back a three year old thread. Doesn't look good for the new guy!!!
