Your other option is Eutronix, as linked to from the top of the BBS. Not as convenient, but they might be faster. For the rotary encoder, you would probably just need to send the display board.

I believe the encoder is all through-the-whole soldering, so you could order one and try and find someone local to you to install it. I'm sure you can find instructions on replacing it if you search the BBS.
