Well...
making your own...is super easy.
I have about 5 that I Gerry rigged..and one that i actually worked on...
you can buy the foam pages and dividers either on ebay or online..
the come in a pack of 4 I believe in the 9 buck range.
And..just find a plain binder anywhere that you like..and add the pages and decorate it..or personalize.
I have found that about 7 or 8 pages[filled with pins] will fit before you explode the binder.
