Reply to Vestax VCM-100

Has anyone here used the VCM-100? Is there any mapping for it and Traktor 3? I didn't find any thread, giving some information about this controller... except for Ean's review. The main question is "Is it worth?". I found it in ebay for about 250$.
I need it for home-use and I find it sufficient as number of controlls... I'm just worried about the mapping.
Thanks everyone.
