I've never heard of a chat filter, but.... I remember buying my Half-Life cd-key on Ebay as a Buy-It-Now. I had one of my brother's disks - he had the platinum pack with 5 games. It cost me like $12 at the time. You could probably find some for cheap...
Well, I checked it out for you (since vectorrecer has reformed me) and I couldn't find any that were sold as a key-only deal. You'll have to buy the entire game.

Let him know you'll be playing it so he won't try to sell it off to someone else.
