I still don't think I understand the product line but it seems there are M7 flats and M7 conicals. And to make it worse there's a flat burr 800W M7 and a flat burr 500W M7 (same burr size). The wattage distinction seems to be the most common point of confusion. The $600 M7's you find are generally the 500W motors. The espressodealer.com overstock listed here is for the 800 watt version.
At least I think that's what I can determine.
And Chriscoffee does sell a stepless kit for it, but you have to call them. Can't just order it via their web forms. Not sure why.
