Everybody is, of course, free to do whatever they want. But if one's goal is to support Marc, perhaps one should ask him which solution he prefers - him spending the money or someone else performing repair work the quality of which he has no way of guaranteeing. A person working on their own FW may cause headaches for him down the line should the unit need further servicing later on. I am not aware of ANY business that would say "yeah, go ahead and DIY that and it'll still be under warranty and we'll still assume liability for mishaps." Maybe such a place exists, but I've never heard of it.
