Wait, shit, I thought the PB frets were stainless? Not that it matters but that's embarassing..
Yeah, I wish!

Just to buy SS fretwire here is $49 + postage for 1.8m. A 21 fret neck takes a minimum of 1.3m, which would work out to over half the price of a $65 PBG neck.

I haven't worked with SS, and doubt I'll ever use it on my own guitars. Having many guitars to play and thus spreading out the "wear & tear", plus having the ability to do refrets myself, I'm happy to just keep going with nickel silver until I'm too old to play anymore or dead (which ever comes first!)
