valdez... i dont think that selling hassalbled/ziess for buying petax is good..lol
i think that the option of using the basic set of hasselblad is the best (u know, camera, weis level finder two backs, and some lenses of your choice). hasselblad is very orgonomic in this combination in my opinion. if u want the light meter u can have the little gossen which is outstanding (there is a topic about it here on apug). and ya rolleiflex is one of the greatest cameras ever, have fun with it, it also capable to produce the top quality (at least the newer ones, so if u are about normal lense it is as good as hasselblad in terms of picture quality, and many times, when u need slower sutter it is even better).
