Sorry, I meant to ask if there were any rigid steel 29ers with a 1x gearing. Redline used to have the D460. I saw one on craigslist I'm considering. And it's a 19".

Guess I'm being pretty particular...I want steel for the comfort, rigid for the weight/maintenance, and some gears for the hills (but just in the back...someone once said rear derailleurs are science and front are voodoo). Seems like a lot of people create 1x9/10's on their own, judging by some of the threads about that kind of conversion...Anyway, it just seems like there is a latent demand for them.

Thanks for all the replies about sizing. The 20" is all they have and it's quite a hike to other dealers. My gut is that 19" is a better fit, though.
