Chris, I called the folks at Santa Cruz and they were happy give me a luthier's discount. I got a set of the "Vintage Style", in gold, with ebony buttons, for $70. To my eye, there is quite a significant difference in the shape of the base plate, and I like these much better than the Grovers. Other than the base plate shape, though, I think they are identical to the Grovers* (as I understand it, Santa Cruz and Grover worked together to develop this tuner design, but I suspect Santa Cruz came up with their base plate shape, in part, to distinguish theirs from the Grovers). I may change my mind depending on customer reaction, but for now, I plan to make these Santa Cruz tuners standard on my guitars. I actually like the way they look a lot better than Waverlys, partly because all the metal parts are the same color (gold), and also the little brackets that hold the worm gear look better to me. It would be premature of me to give a thorough report on how they work, but, except for the occasional bad gear, the first generation worked extremely well; assuming they successfully fixed the problem those had without creating any new problems, these should be stellar.
The other Grovers (the 14:1 ones) you're talking about are an old model and are not in the same league as far as quality is concerned.
If it were up to me, I'd prefer a lower ratio, like 14:1 or 12:1, and I know a lot of players feel the same. The hype about higher ratios is nonsense, IMO. You just have to turn the dang thing more to get in tune, and it doesn't make it any easier to tune accurately. Like so many things, the ability to tune accurately is in the skill of the player, not in the tuning machines. On the other hand, 18:1 doesn't create any big difficulty either; it's only a very minor annoyance, so no big deal. But then Gotoh takes it further to 21:1, and that's just really getting ridiculous. It's one of the things I don't like about the Gotoh contour 510s, the other thing being that they're ugly as sin - formless blobs!

- but I digress...
*Don't quote me on this - I don't know for sure if the latest Grovers incorporate all the mechanical changes that are evident in the Santa Cruz second generation tuners. The change in the worm gear brackets looks identical on both, but I haven't inspected them in detail side-by-side to see if everything is exactly the same.
