mitiempo, I appreciate you taking the time to respond, but those are things I already know.
I'm wondering what a reasonable price is for the nc files and whether or not there are quality differences between sets of files, i.e., are one designer's files as good as another's for their own designs?
FWIW, I believe in NC files usefulness to the extent that if the price is too high I'll go to another
designer - thus my question. Thanks again.
