I could agree more with one exception. I don't think anyone could identify a racket was strung on a KM or the best stringer in the world. I do think it is far easier to have consistancy results with a better machine but I would challenge anyone to tell me which machine a racket was strung on.
Normally I don't reply to these threads about which machine is best for me because only you know the right answer to that question. But if you want the most affordable machine for a home stringer buy a cheap drop weight. If you are going to open a pro shop and will have different people using the same machine and want consistent results in a short period of time cranks and drop weights ahold not be on your list.
Now some are going to say these automatic drop weights are consistent. I am going to say you can't not set a drop weight of any kind to a specific value within +/- 0.1 lb 3 times in a row. Maybe +/- 0.5 lbs would be good. If that's the best you can do then why not just use a normal drop weight and forget paying the extra money for "automatic drop weight" marketing jumbo jumbo.
When you're dead you don't know you're dead. It's the same way when you're stupid.
