I'll be the voice of dissent here...

First off, I have no problem with cold setting frames and have read enough to know it's not a huge deal (and is even reversible). Personally, I'd rather get a 130mm frame if I want a modern drivetrain and I'd leave the classic as is. I do think repsacing to 130mm negatively impacts value (I say this based on experience both buying and selling) and given how many 130 spaced frames are out there, I just don't see the need.
