Magic Bullet

I LOVE my magic bullet.  It really mixes up the powders quickly (10 seconds)  I use it at least twice a day.  I do have a blender, but the bullet is better.  You don't need every container that comes with it, so if you can buy a small set go for it.  You don't need the 21 pc set.  My family likes making frozen margaritas with it.

I don't know about where you live but my Wal Mart carries a magic bullet but it isn't the name brand. You can get it a lot cheaper if that is the route that you end up taking. I never used one, I always used a blender that I got at Wal Mart and paid about $20 for it. I like it, though I don't do shakes any more. I just don't like them since they make me sick to my stomach. Not sure why but they do.

I bought a small individual blender at Walmart for $15.  Hamlton Beach. I think the cup holds about 20 oz which I find to be perfect.  I use it everyday for my protein drinks.  It does fine mixing liquid and soft fruit and even a few small ice cubes.

I'm like Jani....I LOVE my Magic Bullet.     Wish I'd had it before I bought my blender.     It's small and easy to clean plus I love the way it puree's fruit to go in my protien shakes.      I'm glad I'll have it when I get to the soft stage of foods since I'm not a real big "soup" person...     Tina

I've got a stick blender (some call it a "boat motor") that I love. Makes great breakfast smoothies/protein shakes. Puree frozen fruit or a few ice cubes for a thick, icy texture. Include flax seed meal or benefiber, too. Chocolate protein powder and a few frozen sweet cherries blended with water or milk and some raspberry SF syrup . . . 
Sorry, got carried away! Anyway, I like the versatility of the stick blender. Puree a little or a lot, it's super easy to clean, hangs on the wall in its own rack instead of taking counter or cabinet space. Mine came with a 16 oz cup. I do my protein drink and take it with me to drink on the way to work. Breakfast on the go!
Depending on your surgeon's post-op diet plan, you may find it handy to have a means to puree food (soups, etc.) in the weeks after surgery.
Stick blenders can be had for a reasonable price. Got mine years ago, but I think it was around $20 at the time.

I got the off brand one from Wagreens.  It was a lot cheaper and works just as good.  I use mine all the time.
