A couple of things I noted when skimming these reviews. The machine is BIG, so you need space for it. Also it sounds somewhat complicated to thread; you must get each detail of the threading correct. One of the reviewers paid $15,000 for the machine while the other one paid $9,000. The one who paid less called around everywhere to find the lowest price, then got a local dealer to match that price.
