This should be a fun topic!
Boy, your research must make it really difficult to not spend money.
My MIL bought me the magic bullet. I really do like it! I do NOT like it for shredding cheese or veggies though. Cheese ends up in little balls and veggies ends up juice. It is lightening fast so it is a bit hard to control veggies. But it's great for frozen drinks, desserts, salsas....all kinds of things.
I bought a Turbo Cooker once. Now that was stupid buy! It was a long time ago, I can't remember why I hated it, but I gave it away within a month.
