I understand part of the cost argument, but you could also look at it like spending $250 to polish a turd. That $250 is half way to a premium barrel and install job...
No way you're buying a premium barrel and having it installed by a competent smith for $500 unless you are in tight with the smith or are tickling his nuts while you suck on his barrel.
That $250 to rebore may end up shooting better than a custom barrel. It's a gamble and anybody that chooses a rebore fully understands this.
Same with a custom barrel and install.
