I recently saw a cheap 150/250euros manual coil winder on ebay. I have been thinking in building one with step motors but I have been thinking for many years...

have someone experience with it ? would worth it for hobby stuff?

Considering the meager price difference, I would probably choose this one

A hand-crank winding machine is going to be a chore.
Many years ago, I made an experimental winding machine, using two major elements, a variable-speed motor and a mechanical counter. The rest was pieces of wood, aluminium profile and Mecano parts.
I believe today you can find motors with VFD controllers and an electronic rev counter for very little money.
 
I saw a review of that CNC machine it seems to work well. but I feel is too much for my hobby use. it kind of deserve a table. I just need to wind a transformer every few years. I had a winding machine using a electric drill and a calculator as counter it did well for some projects.
 
If you want to wind thin wire and small coil, there is some limitation. The diameter of screw to fix the coil is 10 mm. The mechanical bi-directional limited switch is not so accurate. The lead screw and half nut are not strong enough. The guide head is too loose.
It is not a precision machine or tool. It will work, but we need to use some time to practice, and patience to operate this machine.

I started out with the NZ-5 manual coil winder , I found it for around £20 stg on ebay. 
Its ok for basic random wound coils like chokes but not great for more intricate layered windings .
I'd read up on the NZ-2 and many said the same thing , a bit imprecise and clunky .
I did make up my own winder from a cordless drill and used a plc type counter , the good thing about it was as it was motorised you could concentrate on laying the wire down neatly , where the old hand cranked winder was right hand wind and feed the wire with the left which doesnt feel great to me . In the end I got one of the CNC units from China . I havent done all that much with it , but best layed plans as they say , life stuff has got in the way the last couple of years , once things settle down I hope to get back to winding again in the near future.
