this is good news Stu, thank you.
I've been debating a "restoration" or just waiting for a replacement. 4 years is out a bit, but I think I'll sit tight on the ones I have (I have 2 Paragon machines now). Both have the normal insert cupping, and paint loss around the inserts, plus major ballswirl.

Mine are not anywhere near this bad, but as much as i like playing the game, it could be headed here...look at the wear around the inserts on this example.
