Adapter extras pricing?
 

Well I am looking for some info on what it really costs to have a 35MM adapter working nicely.

I am looking for a flip version, and seriously looking the the letus extreme.

But now the extras I need rails, follow focus, mattebox, anything else?

has anyone bought a whole setup minus lenses, and figured an overall price for a system? Extreme or other?

I will be using it on a XHA1 if that helps any.
