A very relevant topic for me right now since I'm considering moving my US collection from Vario pages to an album. I did look at the Steiner pages as well as the ones on
http://www.philosateleia.com/album/ (which are free). Neither has Scott numbers and are not ordered either.
I have my WW collection in Vario sheets in Lighthouse binders and will wait to see how the US looks on pages

. Now shopping for hinges and mounts.. sighhh. The spending on the 'hobby' never stops!
