AndrewEvery major auction does seem to have a sample of each. ~36 Magie's have been auctioned since 1996 (referenced T206 site and other auction archives), probably about 20 Lajoie's.
I'm slowly dipping my foot into the pre WWII era, the Encyclopedia of BB provided a good education for the layman. Interesting that Lew notes that the Magie might actually be more scarce than the Wagner or Plank.
