Which tripod stabilizer?

I have a set of between-the-tires screw chocks (made them myself from sets of pipe clamps and 4x4's), and they work well. And after speaking with several other guys in the park who have the tripods, most of whom highly recommended them, I've been inclined to try one. I did speak to one guy who said he couldn't tell much difference but that his wife insisted on its use. The JT Strongarms are a good suggestion, just not sure I want to part with that much $$ right now. But I do appreciate the comments and suggestions.
