I wouldn't put off not shooting just to wait for a camera. Seize the moment. What is here today may not be here tomorrow. From a historical standpoint, many people get involved in the format and drop out due to one reason or another. You'll never know if it's for you until you buy something and get going. The camera is just a box to hold a lens and film holder. Buy film, shoot, keep it alive.
I owned a Super Graphic, nice camera but limited in movements. Get something with more options like a true field camera. Just my POV.
