I have an opportunity to purchase a used neos 1000 from a local club that upgraded to a big dawg gamma machine. My question is...what aspects of the machine should I focus my inspection on? I'm sure they will let me take it home and string a few frames on it/put it through the paces. Initial thoughts: -Clamps: hold string secure, move across glide bars smooth -Tension head: again hold string secure, lock out, smooth function, etc. I need to get a tension gauge/calibrator though. What else would the community here suggest I look at closely? Thanks for the help!
