I am well pleased with the Berlbach ball head model I purchased from Calumet. It has two section legs, and is listed as suitable for medium format and small 4x5 cameras. It holds both just fine. The head will not allow moving more than about 30 degrees off vertical, but I dont need that feature for over 90% of my photographing, so it isnt an issue with me. You may want to get the model that has a plain flat head with attaching screw so you can mount the head of your choice. The tripod is well made and finished, and is lighter than my aluminum Tilt-All. It also packs down smaller. I experienced no difference in listed prices with Calumet, and have no hesitation in recommending them.
