I have the magic bullet and it does the job. When I get the big $ together I would love to get the ninja. It depends on your budget.
I'm pre-op too! but I have the ninja and nutribullet I never use my ninja anymore the bullet just blends better and smoother! I use to swear by my ninja until I got my nutribullet!!
