For sale is all of my Really Right Stuff ballheads, clamps included. They've seen some wear, but all are fully functioning.
BH-30 w/ B2-mAS clamp - $125 + Shipping
BH-40 w/ B2-ASII clamp - $215 + Shipping
BH-55 w/ B2-LR II clamp and screw knob panning clamp - $325 + Shipping
The tripod has some wear but all is functioning except the top section of one leg. The antitwist mechanism is no longer working completely, so the leg just turns if you crank down on it too hard...it's never been much of an issue for me. Asking $500 + shipping.
