Of the five 1/72 B-26s (Frog, Revell, Monogram (Snap-Tite), Matchbox, and Airfix), the Airfix is the best. The Frog offering isn't even worth buying for parts, the Revell has lots and lots of rivets, The Matchbox has lots and lots of canyons, The Monogram kit has good basic outline but needs lots of detailing (and is hard to find), leaving you with the Airfix kit, which is relatively easy to find and with very little work can be turned into a very good model.
Hope this has helped.
