I researched wheat grinders online before purchasing. I weighed the pros and cons, then purchased this one. It is a Blendtec/K-Tec.
Pros: lightweight, small, grinds many grains and beans, makes fine flours, internal parts do not need to be cleaned, I have used a similar one before, less expensive than many other grinders
Cons: loud, cannot make cracked wheat
Paying less is always great as long as I am sure it is a quality product. I did not find any reviews with quality concerns. The only thing I was worried about was the noise. I will not be using it that often so it should not be a huge problem. Several of the reviews suggested a solution to the noise. The reviews suggested using it in the garage or outside. As for the cracked wheat, I do not eat it. If it becomes necessary for me to eat cracked wheat, a blender can perform that task.
My plan is to try it out tomorrow. I am excited. I make killer wheat bread and don't get me started on wheat crust pizza!
