Sierra Trading Post has lots of 2 wheel 26" options now - including Travelpro http://www.sierratradingpost.com/rol...uggage~d~4872/

(went through a panicked phase a couple years ago when I couldn't find any 20" 2 wheel carry-ons! But they're still out there too)

Ebags also has a ton listed, including my favorite Eagle Creek (well, they don't have the bag I have since I think it's discontinued now....I rarely use the 26" these days anyway, so it should last a while) http://www.ebags.com/category/luggag...rigin=left_nav
