Hey Zim,
Instroke was originally Instroke of Germany. John Collins from Colorado has owned that title for many years and is the one who recently sold out or became partners with Sterling, I don't know which. Sterling also has the new Fury line of cues. I have heard many wonderful things about those cues. Bob had a chance to play with several of them in Vegas. He liked them very much and they were affordable.
Other case makers include Ron Thomas Cases from LA, Scott Murphey from Texas. If you want more info on Thomas or Murphey, e-mail me and I will get you the info.
Hope this helps!
Eydie
