I found these little Croquis sketchpads at JetPens.com the other day, and I just love them. The Paper is not quite as heavy as the bond in the Moleskines, but they fit very easily into your pocket (unlike the Moleskine). It's great for quick sketches on the fly, and they're cheap. If you haven't been to jetpens, I highly recommend that site. They have stuff from Japan that you can't get in the states, and their variety of pens is amazing.
