Try googling Downtown amiga. They are in Quebec - (after last night's election, they may not be part of North America? The Sepratists have won
) I had him repair my 500 couple years ago. The site itself does not appear overly active, but hi did respond to my email. Joe at Software Hut has a contact as well when I was talking to him a couple years ago that will do repairs on Amigas. Hope this helps.
