All I use are unikeeps. Unikeeps are 100% polypropylene--no acidic materials or moisture absorbing materials, no rusty metal pieces. The unikeep 1.5" binders have straight posts with a flexible cap that snaps into place on top of the post (male-female connector), so there is no ring to get out of alignment from repeated use. I use an 8 x 10 sheet with a piece of backing board in it on the top, or a page lifter, to prevent any rolling of the top page. I like them because they are clamshell design--enclosed on all four sides--so no pages are exposed and they stand up straight. I use 4 pocket sheets with the cards in CardSaver I's to hold the better cards (works for cards up to tall boy size), different configured sheets to hold other cards (like PCs). Since there are no rings, they save a lot of shelf space too.
