The benefits of commissioning have been shared here but it is a lot of money. My thoughts are that if you are fortunate enough to not feel the pain of $1400 and/or not comfortable with performing calibration go for it.

I believe Felder expects buyer to have the machine assembled prior to commissioning. So could one not decide on commissioning after delivery?

Now a days, with a delivery video, it should be easy to show if something arrives damaged. Harder to know issues like AJ though at the time of delivery. Just make sure to note anything out of ordinary no matter how insignificant. For example, on my used K975 purchase, the slider box was delivered upside down because skids came off of the bottom. It also had a hole in ply on one end but it was apparent that nothing was hit. It took me few months to get to the slider as I was out of the country for couple of months after delivery. Anyhow, I found the plate that carries the roller bearings sitting between the slider and it’s base. I had seen the saw prior to delivery, so I am fairly sure this occurred during shipment.

I have had good luck dealing with Felder on accessories that arrived damaged but some here had to go thru a lot to get satisfaction on machines that had issues. I am pretty sure that much more goes right than wrong so you are playing with odds.
