I got a Cuisinart in '84, when I set up my kitchen, and it was the only FP I've had that sliced pepperoni well! Part of the advantage was the push tube - a small one, inside the large one, though I'm not sure they are still made this was. The other was the blades - 1, 1.5, and 2 mm - which were serrated, instead of the smooth, razor like blades, in the KA, and now the Magimix I have. I tossed the slicer blades, so I can't take a photo, but still have the FP! I only use the old one for grinding up things for the garden.
I only got a new one after about 20 years, when the bowl broke for the 3rd time - where it latches onto the base, the plastic was sort of thin. I got 2 more bowls, for $30, but when it doubled to 60, I bought a KA, which was OK, but it leaked around the upper rim - not a frequent problem, but still, not something I wanted. I gave it to someone I knew, setting up their kitchen (who didn't make too much where they had that problem), and got the magimix. Still, nothing has this type of tube, or those serrated blades.
