I am new to blending, but researched them thoroughly before purchasing.  I know this was VERY pricey, but am quite pleased with it so far.  I have nothing to compare it to, so can't say if it is much better than a less expensive brand, but after you-tubing blender comparisons, and reading reviews by blending experts, I decided I was worth it.  I have blended ice and kale (both difficult for other blenders), and have not had a problem.  I know the Ninja brand is much cheaper, and from the reviews I read, does a good job.  The issue with it is that it requires a much longer blending time as compared to the Vita Mix, and that means more oxidation, and that means loss of nutrients.  I figure if I am going to spend the money on the ingredients, and the time preparing them, I want the most bang for my buck and don't like the idea of blending away the good stuff!  Hope this helps anyone considering getting a blender.
