I've looked into this, too. The We R Memory Keepers binders (available on
ebay or
Amazon) are nicely made 3-ring binders, but they lack slipcases (dustcases). They will take Scott Specialty pages, but just barely. Page edges are near the edges of the binder which I don't like.
Also consider Lighthouse Grande binders and Grande G (I think that's what it's called), two somewhat different sizes. One has round rings, the other has rectangular rings. These do have slipcases, and I think Scott pages fit them a bit better than the other binders. If you like 3-ring binders (I don't like them much) this might work well for you.
