I recently bought a Mesu e200 (also know as the Mesu MKII) mount. This mount uses friction rather than gears so doesn’t have any backlash, it is incredibly accurate and can handle a load of 100Kg (that’s 18 stone! or over 200lb!)
Check-out the video for the full unboxing and assembly – the video isn’t a review but you will get an idea of the quality from this video. Whilst the mount is expensive, it is far more economical than equivalent mounts, other owners have sold their Paramount’s in order to fund buying more of these – they really are good.
