I love the look of people shots with a ring flash. but ring flashes are quite expensive. a colleague tipped me off that Rayflash works really well. I took it one step further and was quietly told by someone else that even less expensive than a Rayflash is some cheap made in China knock off called an O-flash. so I ordered one on ebay, $50, total including shipping....and this thing works incredibly well.

so for anyone else wanting a cheap ring flash system for shooting stock instead of spending a ton on a better one, the O-flash is a good little knock off.
