I have a 20+ year old DLC-X food processor. When I first got it, I was doing some catering and really gave it a workout. Over time, some of the plastic parts have cracked, pieces have snapped off, etc. The motor still works fine, but the top and sleeve, and maybe even the bowl, probably need to be replaced. Is it worth replacing these parts, or should I just get a whole new machine? FYI, I don't need the huge capacity X machine any longer--are Cuisinart products still good? If so, which of the current models would you recommend?
