I've just spotted the Kona Sutra. It has VERY low stand-over height as compared to the top-tube length and is spec'd nearly as I'd build it myself. The problem is that no one in the state stocks it in any size.

I did try a 520 earlier today, but it was a 54cm. That was too small (clown bike) so the shop is trying to get a 57cm in for me, but with how little stand-over I had on the 54, I'm worried I won't be able to manage the 57 at all. I must say that I was very impressed with the ride from the cro-mo frame. Even though it was the wrong size, it was rather comfortable.

The LHT is straight out, I think, based on the really high stand-over heights. The Cross-Check comes out a little better, but I'm not sure how good of a touring bike that frame would make.
