There's an app for that
I still have a Cuisinart DLC-10C "Classic" I got in the 1980's from Whole Earth Access Company in Berkeley (remember them, Ralph?) on Ashby. It's made in the USA and has never given any trouble. Oh, the locking tab on the pusher assembly broke a couple of years back. I brought it to TAP Plastics and they sold me a splash of a special solvent for poly carbonate that fixed it perfectly. I was surprised, but the repair has held up just fine.
At the time I bought the Cuisinart I also got every disc the store had in stock. I think that was a good move... have all three slicers, all the shredders/julienne discs. I tried to get a crinkle cut disc but Cuisinart doesn't make them. I have to make do with a Salad Shooter for that (usually I don't even bother with that awkward thing).
Surprisingly, though, my main "slicer" is an old orange plastic Rubbermaid hand operated slicing board (like a fixed thickness mandoline). It does quick work of small quantities of hard veggies like carrots, cucumbers, etc. It's easy to clean up (just a few scrubs under the faucet). It only has one setting but for most quick work that size slice (about 3 mm) is just fine. I've even gotten out my jeweler's files to re-sharpen the fixed blade. Also have a MIU mandoline with multiple blades and adjustable thickness settings, but it's kind of a bother to deal with (although it also will do crinkle cut). Don't ask about the "As Seen on TV" slicing box I got at Grocery Outlet last year. I had hoped it would do ultra think potato slices for home made chips, but it's made of flimsy plastic and the slicing thickness is very dependent upon the amount of force used to push the tater in. Not work the effort, either. The mechanism (lots of gears and such) though is interesting.
I break out the Cuisinart if I have mass quantities to slice or shred. And the KA Mixer shredder/slicer attachment works best for some things like grating Parmesan cheese or laundry soap.
