If you're interested in the nutribullet I'd also suggest getting the Ninja Pulse. It's what I ended up with, the motor is just as good if not a little better, it comes with a large 40 oz (I think) blender top too along with the three to-go cups. I really like it, just a thought
I think I got mine on sale for $65 at Bed Bath and Beyond. They send you 20% off coupons if you have an online membership. I've not tried vitamix or nutribullet, so I can't compare them but I can just tell you that I really like it!!
