I saw that Hilite thread. That's a bit pricey for me, even though I'm already looking at some pretty expensive bikes. The pinion website has this page which allows you to sort through some of the manufacturers, but I can't find anyone offering a stock steel pinion bike with S and S as an option.

That's the rub, isn't it? I'd much rather buy something with the bike designed for couplers and installed as part of the initial build than have them added afterwards.
