I'm thinking about buying one. A quick search looks like they're not cheap so I'd like some firsthand recommendations. Ideally I'm looking for something that can easily be mounted to the tank/tail and tethered. Possibly something like this: https://www.amazon.com/EVO-Gimbals-Wearable-Gimbal-Session/dp/B01K8W0EFK?pf_rd_p=0fc3f2c4-3ed5-4d11-9995-8d7c82394713&pd_rd_wg=qUIsr&pf_rd_r=NH65RHH4VGAHC05FA7HV&ref_=pd_gw_cr_simh&pd_rd_w=kEXpN&pd_rd_r=08061715-a3e1-4e20-bfb4-0e472f873cdb I don't really need a fancy electric motorized one. Do they make a mechanical equivalent of the one above? Any other brands or models I should be looking at? Thanks in advance.
