I've had a few Cokers, I worked in his shop a couple of years ago until I got too busy with tables to commit fulltime anymore.
I tend to like some of his older ones better for playability, and used a cocobolo plainjane with a cocobolo joint.
If you're looking for a good deal on one, I'd talk to Mike at Matador cues, or Jude Hammond with Shaftmaster. He has a beautiful purpleheart Coker that he traded me out of. That's one I should have kept just on looks factor.
Although I have to admit I never used the Coker shafts with it, I had a zshaft that I put on it at Reno last year when I tried selling it to JCIN.
