I have a KO Rapid M and it's a great winter camera, really easy to operate with gloves on.

Regarding the frame spacing issue, I have three backs and they only have frame spacing issues with Fuji films, never with Ilford or Foma/AristaEDU films. I also have a Kiev 6C and again, I only have frame spacing issues with Fuji films, never with other manufacturers. Don't know if anyone else has noticed this, but it's been my experience.
