Valid considerations. It has been many decades since I purchased the Krups slicer. We use it, found it to be a workhorse for home use, easy to clean and we have never bought replacement parts, dropped parts on the floor or used it for any commercial purposes. It fits easily in my pantry as it letter folds. I have sharpened the blade half a dozen times since 1982. We pd less for it new then some models sell today but more than the used prices appearing on the links I offered.
I can’t vouch for any other models. I’ve been very happy with it. The construction is solid.
@DavidPF, what model do you own?
