Speaking of short supply, Warmoth headstock necks are fairly thin on the ground at the moment, too. And I'm thankful for the same reason - I need at least two, and would rather not be tempted at the moment.
But, Warmoth's not doing themselves any favors by keeping things in short supply. The longer you wait around, the more likely it is somebody's gonna put something acceptable up on eBay.
Which brings up a question - has anybody ever seen a Showcase neck with no fret marker inlays? That's an option that I think they ought to leave until order time, like frets, nuts and tuner reams. I don't know how many times I've read where somebody loved a neck, but it had MOP or cream or [whatever] dots and they just couldn't get next to it. I'm guilty of it myself. Then, there are those who'd like a neck with no 'board markers, which is where I'm at now. I mean, if the necks were already fretted I could understand it, but it's not like they couldn't finish them properly - few of those necks have frets on them as they sit.
