the only other I found

I can't help you with ring flashes, but have you thought about getting a second flash and some wireless triggers? Mount these on a bracket, and it may give you more control than a ring flash.
Even the cheap ebay flashes and triggers by Yongnuo might work well?
Have a look at this thread for some more info.
