Cultizm at one point had 1947s in 30 x 38. Wish I'd grabbed those, but I didn't realize the price difference if I logged in with a US account (and it was before I was comfortable breaking the $200 on jeans). It's possible that new runs will offer long inseams as well (though I think they'd shrink to maybe a 35" or 36" inseam). Roy (

If/when he comes back, you probably can't go wrong with Roys (just let him know the length you want post-shrink); I've heard tons of good things about them, and they look pretty fantastic in the fit pics I've seen. Also, oneculture Pulsars (
http://houseofoneculture.wordpress.com) have a 37" inseam. And I'll back up the kudos everyone has given to Ande Whalls. The details are pretty opulent - donut buttons, hidden rivets, selvage fly and belt loops - and they come in more modern cuts than some of the repro-minded Japanese companies.
