I have used the PSI 5/8” crown steb center for about two years. I have not used a Sorby so really can not say the PSI is just as good. I looked at it closely today and the points do show some dulling. I do use it almost exclusively so maybe a Sorby would show the same dulling (or it might be made of a better hardened steel). I have the PSI 1” and do not much care for it. Mostly because I don’t do a lot of large spindles and also I think because the point is so large and the spring so strong, you have to crank on the tailstock pretty good. I have the PSI 60 degree cone live center and have been satisfied with it. But I know it has a cheap bearing and will not likely last. It is just more convenient for me to grab it when I need a cone center then to put the cone on and off of my PM live center. The cone does hold up better with accidents than the aluminum cone for my PM live center which shows some wear on the tip. I also bought the PSI pen mandrel saver. Every one I know who used one complained about the squealing bearing including me. I did just get a nova live center system on sale from WC for $60 which has three bearings and provides the same functionality as the two cheap PSI live centers. Wish I had bought it first. David Ellsworth commented he has been using the Nova center in his shop and classes for 20 years and feels it is the best live center around. To qualify my comments I have been turning five years on a PM3520b and made the video referenced here http://lumberjocks.com/topics/44404

Several folks commented they use an awl to mark centers. I have used that also but have been using a spring loaded center punch and find it so much more convenient.
