I have been given the assignment of purchasing a new CMM. Since I have never done this before and my knowledge is minor I am asking for the help of other professionals in the manufacturing field who have knowledge about CMMs.

1) What is the best CMM on the market?
2) What is the worst?
3) How is the customer service of some dealers after you buy their product and have problems?
4) What are some of the problems?
5) What is your involvement with CMM at this time and in the past?
6) How long have you used CMMs?
7) How many and What kind of CMMs have you used?

Looking for a CMM about 20X20
x18.
TO ALL PROFESSIONALS: I WOULD APPRICIATE YOUR REASONS, LIKES, DISLIKES, ETC. ON ALL AND ANYTHING ABOUT CMMS YOU HAVE AQUIRED THROUGHOUT YOUR CAREERS.

THANK YOU
