I learned about the Glidecam recently. Can be used to give you a very steady camera even if you're running while you shoot. The HD 2000 is highly adjustable DSLR appropriate model. There is an XR (or something like XR) 2000 that has much less adjustability. These things are like $500 for the HD, and $250 for the XR... or if you search Youtube, you can find Zach King's $15 hardware store parts glidecam. This is not as good. Completely skips the gimbal, and just goes for weighted pole with a tripod screw... but hey, it's $15 and does a pretty good job.
