If all else fails I can get you a Griffin Montana Pro Vise or Griffin Odyssey Spider Vise for about $65 plus shipping. I have never put my hands on either of these, but I would think someone on here can tell you if they are good enough or not.
Other Griffin's are a little higher like the Odyssey Cam vise at about $115 plus shipping.
Anyway I don't mind getting one for you if you choose that.
