The Bronica SQ is a wonderful 6x6 system with excellent lenses that are very affordable. I've had the SQ-A, SQ-Ai and SQ-B. The only problem I ever had was with the batteries in my SQ-Ai. Bronica had to compromise the camera to fit in the TTL flash circuitry by switching to four button batteries instead of the standard 6V battery. Button batteries were designed for 1970s 35mm cameras, not 120 SLRs. I finally got so fed up hassling with them that I sold the camera and bought an SQ-B, which I've been very happy with. It you don't need a meter prism that's the model to get. Or else get the motorized winder grip for the SQ-Ai as mentioned earlier.
