If you have had to shoot with a stabilizer for more than 3 minutes straight, you're probably already looking into a Support Vest. The problem is finding a good affordable Support Vest and Stabilizer Kit. I personally won't put my money down on the Flycam Stabilizer Vests. I went for the Steadicam Merlin vest at $1600 dollars, but you'll still be shy of a good Glidecam stabilizer that can run another $400+.
Recently Wondlan has been pushing a bunch of new Single Arm Stabilizer Vest + Stabilizer Kits. These lightweight kits vary in price starting under just $1K depending on what stabilizer is bundled with the vest. Wondlan has a Mini Handheld stabilizer, Carbon Fiber Stabilizer, or larger I-Type. Not too shabby for hopefully the same quality that Wondlan has provided in their past equipment, but I'm still trying to dig up some official reviews on this new gear.
