@Cammy: this is a great thread! And very useful for a lot of people.
I personally know at least 2 persons who are passionate about Amiga, and they are very very talented people. The have repaired all the awfull madness i did trough the last years with my machines, trying to play the role of an engineer or electronic engineer. I suck.

They are also very passionate about other 8/16 bit stuff such as the C=, Atari, MSX, etc. They have even built homemade solutions to be able to use SD cards on the C=, MSX, Ataris and of course Amigas. That, among other stuff i remember (like using optical PC mouse on the Amiga/Commodore)
i know they do this just for hobby. The repairs are not expensive, at least not in my country (Argentina), they are VERY talented and VERY good doing this, and they have many projects to do in the near future, for all kind of machines, focused on Amiga, C=, Atari and MSX, in that order. One is a former local Commodore engineer.
I should ask them if they would be willing to repair stuf from abroad, and of course, if you are willing to send them the stuff so far away (Argentina).
If i have positive news about this, and if you are interested on their services, i will update here
Regards
Sebastian
PD: i also know some polish guy who repairs Amigas, not sure if he is on this forum tough (and maybe some from Czech Republic and/or Hungary). But, dont know if they do massive repairs or they just repair for themselves because lack of time, whi is, usually, one of the most annoying problems many have here
