That sounds reasonable; when I end up with a wonky camera, I'll (intend to) have it repaired if it'll still cost less than buying a working example. My EOS RT was repaired for approximately the same as the purchase price, and although this wasn't the original plan (it was sold as working) I still paid less than I'd find one from, say, AP's advertisers. On the other hand, I haven't bothered doing anything with the EF-M because I could probably get a new one for less than the cost of repair.
