I also have never had an issue with KAI. I've had differences with some of their staff, but never with the company itself or the products that they make. Having said that, I dismissed the ZT product line for a long time not because there was anything wrong with ZT products but simply because ZT products didn't fit my needs. That turned around when ZT released the 0770CF and its variants. My hope is that the 0770CF will be followed by other "underbuilt" offerings from the "overbuilt" company.
