If you email me your postal address ([email protected]) I will send a couple of mk2 rotary encoders to you - I have lots and lots of them. HDD cables are more tricky, Rob has most of the spares and I got left with very few

Reworking them isn't easy, though - it's very easy to lose a pad from the PCB whilst trying to remove the broken encoder. If this happens, a small patch wire fixes it, though it's not desparately neat...
