i honestly would get just a blender. you dont use it for that long. you're only on 100% pure liquid for a few weeks, then you can do particles. they told me how patients would blend pizza, hamburgers, whatever. i never at any point felt the need to do that. i did blend some noodles at some point just to see and oh geez it was awful.
blender is enough for me. i mostly just had milkshakes and mash potatoes and still lost a ton of weight.
