I have a vita-mix, and I will say, I love it! However, I also have dreams of buying a nutrimill for my grinding. The grain gets very hot in the vita-mix, and you can only do small quantities at a time (about 4-6 c total before you need to give the machine a rest). So, if your primary goal is to do lots of grinding, stick with the mill. However, if you will only do smaller amounts of grinding and want a blender with oomph, go with the vita-mix.
