Rob, you can repair the center point. Mount the tailcenter in the drive spindle, wrap tape around the bearing housing and MT shaft so it will "drive",start the lathe and touch it up with a file.
The center point should pop out using the knockout bar,remove the center from the lathe, insert the bar in the hole and tap the point out, I'm sure you can get a new one through Jet.
I have the Nova and Sorby tailcenter sets, both are good.
If you go through Woodcarft, AVOID the "Pro" live center set. It uses a rare earth magnet to hold the tips in, instead of good machining. The tips don't run true.
Phil.
