I have posted this list on a couple of other websites so I thought I would post it here. Hopefully this will come in handy for the newbies here 
I think it might be worthwhile to mention in the OP, that the transaction fees will be quite high, if you're amassing your fortune through faucet sites. That's for the official client at least - others I don't know.
Just sayin'.
