I brought an Osmo mobile 3 for $74.00 since I don't like megatic design, I know it's quick.
OM3 is combo set, that comes with stand ($15~25 over ebay) and a bag. It's an official refurbished also. Good price for $74.
OM4 selling $109, not the cheapest price over OZB, $89.00 ish as lowest price. But you can grab it if you like.
