Raspberry Pi CNC Hat V2.58 gorup buy..anyone interested ?

I saw this Pi CNC Hat V2.58 on eBay and thought it was quite interesting. Maybe a small DIY e3d printer or CD laser etcher .. or small V-carver as well ..not sure but this seems to have all the necessary gumff for a PI CNC ..

The new version in the pic has an on board built in arduino controller and a 4th axis which is apparently an axis clone.

Built in IO software and controller software as in the vid below

I'm not ready to tinker just yet to much on at the moment , but I was thinking about getting one in a few months, so if anyone else was interested I thought I would try a bulk purchase and hopefully bring the price down a bit.. if its only a saving on the $5 P&P. let me know if your interested. I was thinking about getting them sometime in march.
