Therapy, laser, hormones, travel expenses, clothes, and voice therapy have probably cost me in the neighborhood of $10K (Canadian) so far. But, I live in a relatively small (70K people or so) city, so there have been a few things I had to travel for. OHIP covers SRS but assuming I had to pay for that transition would probably cost me around $30-40K when it's all said and done.
EDIT: And that's excluding FFS and BA
