there are, but I haven’t looked at them. Choice did a comparison and Thermomix was rated at 91%, with Tefal cuisine at 82% and KitchenAid 80% - same prices.
As far as “extras” go - yes all sorts of things, but the only one I have bought is the “Cook Key”
many recipes are in the machine, so you have a screen and you page through the recipe.
E.g. it will say add 50g onions (it weighs for you) and a garlic and then you go next and it sets the controls for 3 secs chop at 5. Nothing stopping you just using it and setting the controls yourself, but you get used to having it done for you
. Anyway what they now have is an online recipe site and the cook key attaches to the machine and you can access the site via wifi and download any recipe you like. Also when shopping you can access the site and check what you need to buy. The cook key also allows you to create your own lists, so i have my recipes segmented into things like “soups” “buns” “curry”. etc - makes it easy to select the recipe.
So when I made Mr FM make a Stroganoff the other day, all he had to do was turn on the machine, select the recipe and do what the machine told him - totally idiot proof
