Doesn't sound like an ad to me, sounds like the truth! But then I've also worked with Jean Jacque this year. He brought back my dying A4000 (bad Par: port, sound dying, no battery) and then repaired the '040 card when it failed. (Another EBay machine restored).
I also had a 600 which I'd owned since it was new that popped a capacitor. JJ fixed this up too!
I, like you, have nothing but great things to say about Amiga Center France!
