Max, I think it is wise to try out the cameras first. I'm surprised so many people commented on the weight of a Mamiya TLR system. While I find using it handheld to be clumsy due to the size and apparent topheaviness of the C330, I've never been bothered by the weight of the camera. I have a C330 with 55, 80 and 135 lenses and the bag with this system plus film, filters and extras is really lightweight to this overweight, middle-aged photographer with a bad back and neck.
