I bought this model as a replacement for my old DLC-7 Super Pro that I'd had 30 years.  I wanted something that would use the blades from my old model, and I am pleased to report that this one works.  I might have looked at another model (maybe less expensive) had I not wanted to keep my entire blade collection, but I'm so glad I have this one now.  If it works half as well as the old one, it'll be the last food processor I'll ever have to buy!
