Good luck in Minnesota!
Just completed putting my A4000 back together after a couple of months of repair work. First the motherboard needed refurbishment, and then the CPU card blew. Two trips to France (cause I didn't send the CPU the first time) but it's now it's like new! Certainly better than the day I received it from EBay. For about $400 (ebay fees and refurb costs) I have an excellent A4000!!
BTW, Jean Jacque at Amiga Center France can handle the transaction in English. I never had any problems understanding our emails.
