Has anyone found an alternative or parts list to PPI's $500 steel sleeve kit? I understand that the first and only to it has the right to charge that much, but I just can't believe that no one else has has come up with a similar solution for the 4 or so years PPI's kit has been out.

I feel like this wouldn't be that difficult to create if I could find the proper bore spec to sleeve to.
