I think I paid about $50 for mine. I prefer using the WLF and crank to the prism and grip whenever I dont plan on portait orientation. The view of the ground glass with both eyes open seems more 3d and makes composition easier. The kit is so much lighter too. I sometimes wonder if I should have bought an SQ instead so as to make a WLF more practical, but I tend to more naturally see compositions in a 4:3 ratio, so its etrs for me.
