Good.  I am putting together a parts list for a large(ish) order from
Mouser, but as you know they don't have the transmitter in 315MHz
version, so I'm going to have to get that elsewhere.  Unfortunately,
digikey.ca also doesn't have it in that form factor, so it means more
than one order to have to deal with customs and so on.

That could have been made more clear.  The units I got at Mal-Wart
included the hand-held remote control, as well as the receiver module
which (just) fits within the fan cowling and connects to the fan/lights.
For $25CDN, that's a pretty good deal.
