I love the KMA 3-Rings, ever since my Michaels stopped carrying 3-ring binders. It's super-easy to add, remove, and rearrange pages, and they hold a lot of pages. The extension posts in postbound albums are just too much trouble to mess with, as far as I'm concerned, and postbounds just don't hold as much. With strap-hinge albums it's nearly impossible to add or rearrange pages in the middle of the album. You have to take the whole thing apart. I've been scrapping for almost ten years, and I started with D-ring albums. Once in a while I've considered switching to something different, but then I think carefully about it and decide to stick with my trusty D-ring binders. I would say, definitely get the KMA D-ring albums!
