I had mine replaced in 95, I think. Parts and labor cost me $800, although the guy was a customer of mine and he was doing me "a solid".(hahah) Everyone else wanted around what you were quoted. Make sure they are replacing the glass curtain too(at that price), with glass! Also make sure you get the 10yr top for that price, there isn't that big a difference in price from the different warranty tops. Most of that $1200 is labor.
