Anyone bought or using any of Paul Van Slyke's gear ?
Those in the know will recognise PVS as making what many believe to be the 'ducks nuts' in focusers, rotators, etc. He's a bit of fringe dweller (you'll get this impression when you delve deeper into his web site) but for the man (or woman) who has everything, PVS is nice kit.
It's a long shot, but I'd particularly like to know if anyone has any experience with the "zerotator". His web site (for those interested) is:
