Yeah, Thome is great. There was a good article about him in ESPN the mag a few weeks ago and it made me like him even more.
But, my favorite non-Sox player has to be Melvin Mora. He is a great all around player, outstanding average, good power, good speed, and can play just about every position.
Albert Pujols is also high up on that list. Notice most of the guys I like are 5 tool players, not just a slugger.
