Who do you guys recommend for CZ slide milling?

Looking to get a CZ-P07 and am looking into putting a dot on it. I looked at ATEi, but they didn't have any CZs listed. It looks like Cajun Gunworks mills slides, and Primary Machine also offers CZ slide milling. I know that the P&S community generally holds CGW in high regard, but other people say that Primary Machine is who I should be looking into. Is there another quality miller that I should know about?

Since ATEi isn't an option, who do I go with?
