I have had three brands of food processors and Magimix are so much more effecient and powerful than the others, I wouldn't look at anything else. Plus you can always get spares online.
I finally decided to upgrade my 26 year old Magimix (three new bowls but no mechanical failures!); I have to say this is on the whole worthwhile.
The pulse /on/off is easier to use and to keep clean.
The three bowl sizes make chopping the right quantity easier
The smallest bowl is superb for sauces, especially sauce tartare.
The dough blade is probably better for dough than the steel, and I can make a 500gram mix in the biggest bowl.
The optional Julienne and french-fry disks are excellent, make very attractive crudites as well as soup or casserole ingredients ( optional extras)
The fine grater/ slicer (they are combined as a reversible disk)is not as fine slicing as the previous model, though the grating is okay
The egg whisk takes ages - much easier by hand or with an old-fashioned electric whisk
The lid has a very awkward small space between the funnel and the edge which is only accessible with a tooth-brush and gets dirty every time.
