Some of the videos I watched on youtube to help me find an affordable rig to allow for smoother handheld shots for an upcoming project. There are also a number of DIY options. I ended up buying the Spider Steady. It cost me about $40 and has a few different setups.
And the video below is just a cool setup that came out of the recent NAB Show. IT had no bearing on what I ended up purchasing because this is expensive... but it looks fun.
