Certainly cost would be a consideration for any purchase. However, using your original analogy of the Bugatti at $2.2m and a grinder at $700, does not find the two on par. Factoring the Bugatti by 100 leaves $22,000 which will buy an average automobile. Factoring the $700 grinder by 100 leaves $7 for a grinder - not even enough for an average whirly blade. Granted we haven't considered budgetary restrictions. If those restrictions find your method of transportation to be primarily bipedal, or a relative automotive budget of $0, then there is absolutely no cost justification for any grinder using the same criteria. I believe your intentions were to come in and blow hooey on a high end commercial grinder purchase. If not I'm at a loss to what bits of information you hope to glean.
