Mike, check out:

This one has a "clicker" but as someone mentioned here you can get one
for a buck or two that does not click and will likely drop into the PC
board pattern. The price is right and although I don't have one, I do
have it's sibling in the QRX transceiver which works like a charm (both
VFO and transceiver) Any time you want you can replace the low cost
encoder with an optical encoder like on the higher end radios.
I'm thinking of using one for my Corsair II by replacing the PTO in the
remote VFO with one of these. Have a few other projects to complete
first though.

Aloha Curt!
Have you looked at the AQRP VFO?
$40.
Si570 based.
http://www.qsl.net/k5bcq/Kits/Kits.html
PA0KLT VFO kit.
$45 or so (price is in pound sterling)
Si570 based.

The above two kits are quite similar.
I have the AQRP. Not using with a Tentec. It's my signal generator
for the
shack :-)
I've just ordered a VNA kit from AQRP. It's VIA on the web site but
they've
recently added I/O ports.
The only part of the AQRP kit I found challenging was soldering the
Si570
chip. Missed a pad on the first go around. Rumor is that Kees is
coming out
wit a smaller version of his VFO so you may want to ask before you
order.
The display might be small enough to fit the window on the C21.
Then there is the qrp labs kit. It's only $33
Si5351a based.

You could really hotrod that C21. take a look at the manual for the
QRP
labs QCX transceiver for some ideas.
