i don't have one but I think it depends on how you like to cook and the type of food you like to eat as to whether its worthwhile. ie if you are into soups, icecreams, custards, purees, slushies or even ****tails, sauces etc I can see them being worthwhile and I know thus they could develop other ingredients well for other recipes eg fruit purees to use in muffins etc but weren't they at full price uptowards $2K unless you became a "dealer" (I could be very wrong here). I just can't see me getting my $2K out of it because I don't/make a lot of the above. I know a couple of people who have them and love them but they aren't big from scratch cooks so to be able to put a pile of stuff in and come out with the above things is great for them. i could be very wrong about the limitations mentioned above and the price but that was my understanding of them
