If you have a few extra bucks, you could send it to Jurgen to let him work his magic. I've purchased a couple folders from him over the past few years and sent one for CLA. I've only had good experiences with him and his work. He's on Ebay as "certo6". He sells his refurbished cameras on there from time to time.

Hope this helps.
