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 where you can find what looks like the exact same camera cranes for sometimes less than half the price (including pan head and tripod).
