They saw the new Zhiyun Crane 2S and cried!

eBay does not even try to protect sellers. If I'm selling a high value item I make it clear that not only is it 'Collection only'... you MUST come and inspect and ONLY THEN pay. Takes longer to sell but only 'serious' people will contact you.
Recently sold my BMPCC V1 and Micro and Metabones... each buyer came and picked up and that, since there were no fees to pay, practically covered my 2 Pocket4K cams.
Was stung a few years years ago on my Canon 60D... got the camera back with a broken screen and lost the fees to eBay - NEVER again. I'm not much of a seller but once it has a 'highish' value then eBay is just an advertising platform for me.

Finally!! Well done. Can't wait to see it!!

For the UK folks there is 50% off the Ursa Mini 4.6K PL mount @ ProAV
*NOTE - PL mount 'ONLY!'

Whoa that is small. Very nice!

I seriously doubt this will be in the Zoom H1 price range... probably more like 3-5 times that amount.
