If you're interested in Lead and Gold or Trine, take a look at my reviews at those links.  They're both great games.  Lead and Gold has online multi-player, so it's an excellent choice for a gift pack to share with your Steam friends.

If you're unfamiliar with the games in the Indie Air Pack, take a look at my reviews of Altitude, DogFighter, and Plain Sight.  These are all online multi-player games that I highly recommend as well.

If you're looking for an individual copy of World of Goo, GamersGate has it for $2.49.  Amazon has Trine for  $6.45.
