Unfortunately I don't have the time, resources, and most important of all, the skill to take on building one from parts...unless it snaps together
If I could, that's what I would do.
For some reason I can't really explain...I don't trust anyone else to build it for me. Friends have offered but I don't know how good they are either.
I want a Fender.
There was an Ebay sale a while back where a guy sort of implied that the piece he was selling was built for him by Warmouth with Fender authorization. That would be the perfect solution for me to have it done that way but it turned out to be a bogus claim.
So it looks like I'm back to square 1 if a righty is not a good way to go.
The day after I go to that great bass clef in the sky, Fender will probably come out with a beautiful lefty SCPB reissue.
