I use this hobby level crimper from Servo City. Price is right; although, I have not used it with Molex-brand pins. It does handle that gauge wire and I prefer it to the single-action Radio Shack crimper.
I bought mine new from digikey... it's the only way to be sure you're getting what is the right tool for the flavor of connector you are using. I bought one handle and two heads, one for .100 and one for .156, as I use both types of connectors.
I am not familiar with the KK terminology either.
go to the molex website, find out what is the tool for use with your connector, and then match it on ebay.
I use it almost exclusively for servo connectors. It works fine for me and has a nice curled crimp on the wire. The pins I use are berg 48234-000 or similar (**broken link removed** ). I don't use Molex with it. When I use Molex, they are larger, and I use a different crimper.
