A Magimix is great. I've had the same one for 30 years and the main reason I bought it was to mince my own meat - you know what you're getting then! The motor is extremely powerful and the Sabatier cutting blade is sharp
I use it to make pastry (great, quick) and to grate/slice/chop veg. So, for example, when you're cooking and to minimise washing up, you might slice veg for a coleslaw and then parsley for a stew...and then garlic and ginger together if you're making a curry etc. It's also great for whizzing up a tin of good tomatoes for a sauce (again, you know what you're getting). You can whiz up pizza dough quickly or enough dough for a small loaf. You'd get most out of it if you plan your food prep/cooking session in advance so you can use it to prepare a whole raft of things in advance.
So, it is economical and you know what you're getting in terms of your prime ingredients. It doesn't take up a lot of space and it saves time too.
The downside is you must not put the mixing bowl in the dishwasher. I know you are supposed to be able to but it weakens the bowl. That said, 25 years ago I noticed the bowl was degrading a bit in the dishwasher so I stopped putting it in. That bowl finally gave up the ghost last year and I had to have a replacement.
You can, however, put the blades/attachments in the dishwasher.
If you have all the kitchen basics, have some spare cash (or a birthday coming up) then this is a wise investment if you like making things from scratch.
