I think Aragorn is the best so far, and Legolas was the only other one that appealed to me to buy. I'd like Boromir, but the exclusive isn't a must for me, same as the ringwraith, so i'm happy to wait until they ship and hopefully pick one of each up locally.
Shame Gimli didn't do anything for me, but i guess Frodo/Sam and Merry/Pippin will be happy with them. I really can't wait to see what they look like.
