also the Gemini 2 currently does not support the encoders (although the port is there).

You can try to get a set of encoders from JMI.
As Orlyandico said, the original Losmandy encoders haven't been made in years & are becoming harder to find. There have been a number of requests to Losmandy to put them back into production but so far they haven't. It would be nice, & they do work very well.
If you get encoders, the older Gemini-1 system does support those, & more of them are coming on the market as the owners change over to Gemini-2. The new Gemini-2 will support encoders eventually, but Rene' Goerlich hasn't written the code yet. He has been adding features (PEC, PAA, PAS, etc.) and debugging them as the firmware gets developed. External encoders is on the list of features that G2 will support.
I have an older HGM-200 & G11, both with the external encoders. The G11 has G1 & directly reads the encoders fine. The HGM I've put my old Sky-Commander back in service for the external encoder interface. I do outreach with the BSA & the Cubscouts invariably put their hands on the OTA & push it off target. Not having Encoders is not really an option. Good luck.

that said, i have read so many instances that the slip clutches get finicky, you have to replace the cork every so often, etc.
IMHO the old AP mounts have the nicest encoder interfaces, they look integrated with the mount. Pricey (for a 20-year old mount) though and quite rare.
the Argo Navis seems to be the best bet in DSC's. I'm beginning to think I should have bought one instead of converting my AP600E to GoTo...

I have a GM-8 with encoders and it's a great little system. I like it for public outreach because if someone grabs the scope, I can easily get it back on target. BTW - there is no cork in my Losmandy mount.

Any encoder can be made to work.

Doesn't use a worm wheel and large payload. Not cheap though. I was looking at this mount instead of a Mach1 but at the end of the day, old but proven technology wins over promising new but not quite mature technology. Particularly when you're forking out that much moolah...
