"Eye of Judgment", that crazy card-game / eye toy thing was $34.99 at Target in North Carolina today - complete with a camera, camera stand, mat, and enough cards to get started.  I picked it up and was able to get the hang of it in a couple hours.  You may want to call your local Target to see if this is a national price -  I don't think this is gonna get re-stocked at that price.

There is multi-player on the internet.  You can't even see anything from the other guy's camera, just the monsters and spells that show up.  As for razors, the camera can't tell the difference between real cards and cards you just print off the internet (I was able to find copies of all 120 Set One cards including "super rare" cards after a 5 minute search).  They give you enough cards to experiment with - since printing them out isn't that much cheaper than buying the cards, I might spend 10-15 bucks on cards after I get better at the game so I can customize my deck to have more mid-range monsters and less complicated spells.  Anybody who wants to play me should email karatedogpodcast@yahoo.com, we can use skype because I don't have a headset for the PS3.  Kevin, let me know if you get it.
