Haha I'll concede you that, to be sure--if I match, I'm sure the registration fee will be about the last thing on my mind.
If you don't mind my asking, did you end up going through the match, or did you take one of the non-match offers? And was this before APPIC/APPCN allowed you to ask for a "matching offer" from match site(s) if you had one in hand from a non-match fellowship?
Feel free to PM if you'd be more comfortable with that. Not trying to be nosy, just looking to get my bearings.
