Kyocera repair/restoration

At the risk of being flamed, can anyone recommend an excellent technician or shop to repair my beloved Kyocera D-811 cassette deck?  The last technician to touch it was Steven Sank, but he's apparently had a career change and is now making custom mics.

I've also got a Kyocera DA-510cx CD player that needs work, though I'm not sure it would be worth the cost to repair.  It won't read any discs, and the tray needs a little help to open.  Thoughts and suggestions would be welcome.  No trolls, please.
