I'm sure this has been asked before, but I couldn't find anything in the searches. I'm looking for a universal (Arca Swiss?) quick release plate and base combo. I have an Alien Bees Ringflash that I would mount the catch/base plate mechanism on. Suggest brands or models. I'm not looking to spend more than $20-30 per plate, and not more than $40 for the base mechanism, otherwise I'd go with the Really Right Stuff plates.
