I have the B87-b portrait flash bracket with mounting rail. If you go to the RRS website it is the B78-b portrait package. This is not the new version that they just came out with. From what I can tell the only difference is the mount for the flash is styled different. I'd like to get $275 shipped and paypal'd for this. There is not a mark on either piece.
Also a Benro KJ-2. Like new only used for a week. One small pen sized nick where the camera bracket slides in. Held my d2x and 17-55mm fine with the RRS L bracket. $100 shipped and Paypal'd.
I have some references from other sites if needed.
