Jags,
So sorry this last bit of interest came up short, but I agree with Rual -- give it a bit more time. Not everyone checks the Forum all the time, and guests come and go. Sometimes, it can take a few weeks, or you can pump up interest after several weeks with a fresh reply to bring it to the top of the boards again.
Also, weather can play a role. You've had some nice days recently, so people are out and about more and away from the computer. That can be enough to fire interest in bike touring when they return.
Have you placed an ad on the CTC forum and some of the other Fora you monitor? The more exposure, the better.
Thorn will still produce a popular bike like the Audax for awhile yet, so it's not like the only example is winging its way farther from your grasp. Now you know your size for sure (always a useful thing), you can watch the boards, eBay, and Gumtree -- a really nice used frame/fork set might come available. One never knows.
Best,
Dan.
