A third shout-out for Ultra Pro! I use clear sleeves as well, for the same reason as Feesh.
I have experience with the FFG sleeves. I originally sleeved my core set in them. After using Ultra Pro on a different game, once I started buying Data Packs, I switched over to Ultra Pro (meaning that I unsleeved all my core set from FFG's sleeves and re-sleeved them with Ultra Pro sleeves--they're that much better).
The problem with FFG's sleeves is that that are really big. Like they don't even feel designed for these cards (and I did get the right FFG sleeves for ANR). Ultra Pro fits tight and feels a little thicker. Plus you can buy big boxes of it on ebay for a pretty cheap per-pack price. Stick with a company that's been doing this for a long time. This is generally a good idea when it comes to accessories and storage for games--I find the companies that make the games usually don't do the secondary market stuff as well as other companies.
I store my cards in traditional long cardboard trading card boxes. I never need to bring them all when I play, and even if I did (for a deckbuilding session with friends, say), I have one box each for Corp and Runner, with all cards released so far sleeved, so it's reasonably portable.
I use these things for my decks, since they are compact and I can fit a Corp deck and a Runner deck, separated, in one package. It's almost like these deckboxes were designed for Netrunner.
