Besides the affordable price, the new Wieldy has several features the Glidecam HD series stabilizer don't provide such as an adjustable Gimbal, non-rotating sled, and carbon fiber post. Other popular features found on the more expensive Glidecam HD like fine-tuning knobs (trim), adjustable sled weights, and quick release stage has been designed into this Wieldy almost exactly. Overall a great product for the price, and it performs well. Additional information, photos, and other video examples of the Carbon Wieldy Stabilizer in use can be seen following the link to the product page via eBay (Click Here).

You can also find the Wieldy bundled with a dual arm stabilizer from another seller. It's being rebranded under the name 'CAME' (terrible name). A few listings from this seller show the dual arm vest bundled with this same Wieldy Carbon Fiber stabilizer (Click Here).

The Skyler MiniCam (seen above) is one of the smallest Video Camera Stabilizers around, and can still fly a fairly weighted DSLR Camera. It's an expensive piece of kit, but my favorite stabilizer to travel with. To make the Skyler even smaller and faster to setup, there's a new optional Transformer Legs kit. It allows you to fold the three counterweight legs instead of unscrewing each one on the for the Skyler MiniCam Video Camera Stabilizer.
Vimeo member Switch Flick uses pieces from a Flycam Nano to make a DIY Spidertrax Rotating Dolly. Axles are a bit long on this first version, but it looks pretty legit with attention to details down to the bolts (much like I used in my setup). Of course, this is all assuming you've already dished out a bit of change for the Nano.
If you're not familiar with the Flycam Nano, another video was recently shot using a Canon 5D Mark II + 17-40mm F/4L + Rode Video Mic. That's quite a bit of weight, but Vimeo member Spencer Turley managed to pull off some great footage while doing some charitable work out in Tuvalu. Found here: http://www.vimeo.com/20742652
There's plenty of stabilizers on the market in all different shapes and sizes, but finding one to support up to 8lbs. of weight narrows the playing field. Now when you're talking about finding a portable lightweight stabilizer + carry 8lbs. the list gets even smaller. The Steadicam Merlin is one of the best performing portable stabilizers i've used, but has specs to support only up to 5lbs for about $800 dollars, the Glidecam 2000 up to 6lbs, and The Glidecam 4000 can support up to 10lbs for about $550.
The Blackbird stabilizer from Camera Motion Research is said to support up to 8lbs, is cheaper in price, and less than half the weight and size (making great for traveling) compared to the Glidecam HD4000. The Gimbal handle design with universal joint is found on other stabilizers, but this is the largest one i've seen. How well does it perform? Well, there's videos of this stabilizer flying a Sony EX1 so any DSLR should be a breeze. Just by looking at the build quality, there's quite a bit of thought placed into every detail about how this thing works. The stage has a quick release system, can be adjusted forward / back, and left / right with fine tuning knobs. The weights on the bottom are mounted to an adjustable post with clear markings for easy repositioning if you have to take the unit apart. (I often use nail polish on my Glidecam posts to make sure I can line things back up) One interesting feature addresses problems with what most people have issues with (stabilizer roll). By adjusting friction into the Gimbal it keeps the stabilizer horizon more consistent.
If you understand stabilizers, how they work, this one is clearly made to address all concerns for getting the camera quickly balanced, easy to fly, and travel light. I'll be putting it together and testing it out later this week, but so far it looks like a great little product. I'll have part #2 of this review up soon.
