Joe,
Usually when someone post a question like this they'll get three pages of answers, I dont know what the deal is.

JJ Perodeau is good, no make that excellent
Jack Rowe is on the level but not sure if he's still "doing it"
NECG does alot of repair work on Spanish guns, they can help you out too, they've done warranty work for me on a AyA #2 with ejector problems...gun was back in a week and worked flawlessly.

If it was my gun...I would probably send it to NECG for the work.

Hope this helps,
Dustin
