I had been wanting to for a long, long time but I finally spent the bucks for a truly top line frying pan.
Gives the best test information on on cookware of all those I looked at, and there are some good ones if you sift through the ones that say really nothing except to push the ones they want to.
I ordered a Demeyere from Zwilling on line and paid 99 bucks, on sale, for a 9.5 frying pan , whose list price is 275 bucks, on Ebay.
Demeyere and All-Clad seem to be the best two out there and this site tells why they are or are not at the top of the list.
From all sites I have looked at the main complaint for cast iron is weight, especially on the large items.
I also read on several sites that there is NO such thing as a heirloom non-stick, they all have a limited life no matter how much you pay and if you are going to spend big bucks you should get one that can last a life time.
One thing several sites also said that if you get a frying, especially a high priced one, READ the instructions on how it should be used, especially when you first use it.
Many people have ruined very high price cook wear because they did not.
Oddly this brand has a 30 year warranty but another brand , if the cook ware is used at home, and not in a professional kitchen the warranty is voided.
