I've been using Lighthouse stockbooks as I revive my collection but one limitation I found is that the fixed number of pages means either I have to cut off a country earlier than I might wish or have extra blank pages because a coutry is too big for 16 page book but too small for a 32.
Also discovered that Vario pages have come down quite a bit in price from some online retailers, to as low as US$15 for
a 5-pack 25 pages (5 packs of 5) of double sided pages.
Just got my first supply of Varios in stock and...I'm a convert! The stamps look great, and the flexibility of the loose-leaf format is a wonderful new removal of limitations.

Page from my Algeria collection I am currently transporting over. One of my favorite French colonial sets. Just lack 3 values to complete.
