Vimeo member Zolinger puts up an example of a compact video jib. Pretty cool stuff, but I have to say it looks very very close to some other models available on eBay for about half the price. You make the decision.
Here's a link to Zolinger's eBay store (click here)
Zolinger Camera Jib.
Here's where you can find what looks like the exact same camera cranes for sometimes less than half the price (including pan head and tripod).

The 717AH is back and with a slight price drop. [Thanks Larry]. This is a solid and inexpensive mount for the top of your sliders or track dollies that help to reduce vibration during your movements. It's also helpful to be able to change pan and tilt angles. You'll find this head on many DIY projects including Rod's DIY Ladder dolly. You can find the discounted 717AH following the link (click here).
Fluid Drag Tripod Head 717AH
Vimeo member Jonathan Nicol throws up a review on the Fancier FC-02H video fluid head. I guess this is supposed to be a step above the typical 717 heads. There's some samples at the end of his video review, and the samples do look smooth indeed. I couldn't locate this particular model on eBay, but it looks like the FC-02H head could be mounted on different tripods and coming up with different model numbers.
There's two different version over on Amazon, and from the image appears to be the FC-02H head (75mm Bowl Mount). Although these heads may provide smooth movements, keep in mind that bowl mounts are not the ones that make it easy for you to remove and use on Sliders. These are best used as just straight up fluid head sticks.

A more expensive version also exists, it appears to be the same head, but possibly a different Tripod.

With the new Konova slider on the market the 717AH fluid head has become a popular accessory to complete the set. Recently there seems to be a small price drop in the WF717A Tripod + Fluid Head via Amazon. Unlike the bowl mount Fluid head, the one on the WF717A (this one) can be removed and used on your Konova slider, SpiderTrax Skate dolly, or other projects and you'll still have a very lightweight aluminum tripod + bag. Should be a standard 3/8" threaded mount.
