I think 2x2s in 20 pocket pages are an excellent choice. Also check on
ebay.
That website looks like its got decent prices on 2x2s. I rarely buy 2x2s because when I do, I buy a lot of them (10,000). That gives me a decent price break on them and more importantly, I don't ever run out (I really hate it when that happens). I've got thousands of coins stored this way and I couldn't afford to do it any other way. Plus it is very easy to pull out a binder and search through them.
Note that there are two different weights of 20 pocket pages. There is a light weight that can cost about $.10-$.20 each. There is also a heavy weight that can cost $.80-$1.00 each. The light weight is good for dimes, cents, nickles. The heavy weight is a must for halves or dollars. Quarters can go either way. Putting dimes in the heavy page is a waste of money. Putting dollars in the light weight page is a mess because they are so heavy they hang funny and tear the pages.
