King has been around for years and is sold under a slew of brand names including Delta. I have their 16" planer and worked the living snot out of it pushing several thousand feet of rough sawn fir, cedar, pine, spruce, and birch through it. It takes off 1/8" per pass even at 16" wide. Still going strong after about 20 years. I also have their 108" x 6" vertical belt sander. Also 20 years old and going strong but not used nearly as much as the planer. I just bought a 16/32 drum sander from them and it is working well. They sell some fairly serious table saws, comparable to what you would get from Grizzly (might be the same factory). Whether that is one of them I can't say. But just because it is a King brand doesn't mean it's defective. It just isn't top of the line.
As far as the CS, I did have an issue with the table on the sander. It wasn't perpendicular to the sanding belt. I called them and complained and they did hem and haw but they did make it right by sending me a new table that was 90* to the belt. The planer head wasn't parallel to the table but I adjusted that. That is my experience with King. So far at least.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
