Just bought this K5 Slider from Konova and it's really for the money I spent, really smooth and well made, very impressed with this. Put a Gitzo head on the slider and it's really very very smooth when doing camera movements. A keeper for me. If you decide to get one you should from their direct website, Ebay doesn't give you a choice of sizes, I got the 120cm one. 4 ft. But the K3 slider is a lighter weight product, might not work for EPIC or Scarlet.
