Thanks a lot for all your comments, gang! I was leaning towards passing on both of those highly-desired options... but your comments -and those of my girlfriend, who agrees- encourage me to go forward with both.
I'm now leaning towards getting both. I know if I get both, I'll be 100% satisfied. The package, as is, is awesome. But if I can get the extended fingerboard, that would be... well, I'm just used to the range. I'd be dissatisfied without it. And the neck... I've got something special in mind, unique, but no harder to build than a standard neck. I figured there would be no upcharge other than (for) the ebony... but I figured wrong! Valentino told me they don't order the long pieces for the neck standard, and it would be a big upcharge... but I'd still love to have the mahogany in the neck -for the outer two laminates... my understanding is that these two mahogany laminates, the largest two of the neck, sandwiched between BTC coco bolo front and rear, would really further the coco bolo sound, possibly transmitting it up the neck...!
And there's another detail to the neck that I want to keep a surprise, 'cause if I do it, it'll be especially unique and stunning.
I'm leaning towards doing it... I've got to decide what I'm going to do real soon... Valentino delivered the quote Wednesday, and told me to mull it over and get back to him on Monday. They're honoring the monthly special in effect when I submitted my quote, but now that I've got my quote, I'm obliged to decide quickly as they surely can't honor it indefinitely. So I'm going to make my decision Monday... at this point it'll be to go with the extra two features, cost be damned! I'll ask 'em for a formal written quote, and I'll e-mail the same quote all up front to 3 dealers and take the best initial offer -no back and forth, or yanking them. My understanding is that the top Alembic dealers offer 25% off -but can not, by dealer agreement, offer more, so the least expensive dealer quote that is at least 22&1/2% off will be what I go for -if I don't get at least 22.5% off, I'll keep looking.
Anyway, I won't waste anyones time, and I'll be up front with everyone. I'll openly share the quote from Alembic with them, calculator in hand with the quote generator in front of me, and all they'll need to do is confirm the quote -especially the custom details not itemizable on the quote generator- with Alembic. There will NOT be any nonsense wasting Alembic's time with quoting the same instrument all over, nor will there be any back and forthing on my part to whittle down $50 dollars or $100 dollars. As long as I get at least 90% of the maximum discount (frankly, I've really got my heart set ON the maximum... any dealer will be doing okay with this one at 75% list price, I'm sure), then I'll take the best bid, and won't break anyone's... you know whats... for $50 or $100 buck savings.
Thanks again for your comments, guys. Especially your reassurance about production time, Bill. Of course, the other edge of the sword is that the faster I get it, the faster I have to put the balance on my credit card and have to pay it off. (The good news is I've already got 25% cash saved up, I'm debt-free, and I've got great credit. I'd likely have the deposit paid off by the time I get the bass, and the other half wouldn't be that scary.)
I'll keep you guys informed!
