The Skyler MiniCam has been a work in progress floating around the Internet for a very long time, but this is the first time i've seen it available on eBay. A clever little stabilizer which stands on it's own like a tripod, looks to have great build quality, and very simple fine tuning knobs. A 1/4-20 thread under the stabilizer allows you to mount it on a Monopod so that you can don't need to dismount your camera.
Unfortunately the asking price of over $620 dollars is a big umm..'heck no' for me. It's too bad they couldn't get the Skyler under the $200 dollar price tag, I think it could be a hit. I guess if you want to compare the price to an $800 dollar Steadicam Merlin, it's not looking so bad, but there's so many more stabilizer options now for under $300 dollars. If you're still curious, there's some additional demo videos of the Skyler MiniCam stabilizer in use over at the auction page (click here).
