Thank you everyone for the great feedback you guys are really helping out !
The combo I use is the Nikon D750 + Tamron 24-70mm F/2.8 and in terms of lighting everything is Aputure.
The C500 I have yet to find one in that price range, but then again if im going to invest so much in a new camera id much rather get a new unit with warranty, and somewhere close in case there's any problem I can just hop to the place i bought it and get it fixed.
Yeah size is a concern, Id hate to have something like excess weight slowing me down.
Starting to lean more towards the C100 II but haven't really made up my mind yet.
