I didn't buy the Starlite Jeff because I don't use the Zone System as such personally' but I tried all the top of the range light meters hands on at my local pro dealers before I actually bought a Kenko KFM 2100 http://kenkoglobal.com/kfm-2100.html ( formally the Minolta Flash meter V1) proved to be perfect for my requirements, but if I was A Zoner in particular I would have got the Gossen.
