Here's a recent video showing how to set up and balance the budget Single Arm Vest system with Carbon Stabilizer. I actually have this vest (not the stabilizer) and I feel it's pretty good quality, but I had trouble getting a lightweight setup on the single arm vest to work smoothly and get rid of that slight Pogo effect. In this video they have a fairly heavy Matte Box to add another few pounds of weight to the basic camera.
There's no sample footage from the system, but it's a pretty good instructional 'How to Setup and Balance a Steadicam' video that applies to most stabilizers on the market. This particular one shown in the video can be found for under $600 bucks complete via eBay (Click Here)
