Is anyone using a non Zenmuse H3-2D gimbal? I know there are some out there but the board won't let me search "gimbal". I'm wondering if there is a cheaper, alternative gimbal that will hold me over until I shell out for the Zenmuse. And, are any of these alternative gimbals plug and play like the Zenmuse? I see a ton on ebay and such but have no clue if they are worth anything.
