One essential tool for long Flying Video Stabilizer (Steadicam) type shots is a Vest system with an iso-elastic arm. The vest helps to take the weight of the camera off the arms and distributes the load over to the body. The flexible spring loaded iso-elastic arm keeps the camera level as the operator runs, jumps, or climbs a flight of stairs.
The problem has always been that the price of these vest systems were often out of reach. Here's a new Single ISO Arm Camera Load Vest System on the market that appeared recently. Quality, Style, and build looks much sturdier than the ugly Flycam Vest system (seen here), and this new vest runs just under $370. That's cheaper than a basic Rokinon Cine Lens. You can find the new vest available via eBay (Click Here).
