There are quite a few good running replica's on the for sale section of this site. Many are factory rollers or turn keys. The more factory built they are (as a rule) the better! $40K to 100K will buy you an awsome AC!! Depending on what your after. The best lower budgit (top quality) kit IMO, would be the FFR MKIV if you are determined to build. But you will still end up over $40K min.for a quality self build
