Can a worn Komatsu PC200 bucket pin be rebuilt, or is replacement the better option?

[Mc Wyndell]

I'm working on the bucket linkage on my Komatsu PC200 and found that the main bucket pin is worn. The stick bushings still look pretty good, but a new pin is over $1,200. Has anyone had a worn pin welded up and machined back to size, or is it better to just replace it? Also curious if aftermarket pins and bushings are worth considering.
