Hi! Welcome to DC. I also have an N50, and lucked into both a roto and a pelican. After some use, I sold the roto on ebay, and still use the pelican. Mine was sitting in a garage with all four disks and the pusher, and i like it...a lot. I also have a metal chute that clips onto the edge of the mixing bowl, so everything comes out the bottom of the pelican and into the bowl. Very neat. The pelican came with an adjustable slicing disk, fine and coarse shredding disks, and an ice crushing disk which pulps tomatoes beautifully. Beside the pelican part, there is a stright feed tube, great for pepperoni, carrots, summer sausage...anything that shape.
