Get the biggest, heaviest band saw you can afford. It really is worth it. Big bandsaws are just plain effortless to use, and the extra mass makes them run smoother. I have a 16" Walker Turner, and to me it is the bare minimum. Its a wonderful, smooth running saw, but I would go for a 20" or bigger if I had the space. It isn't a question of power- 2hp on a bandsaw is plenty for just about any vertical bandsaw, its the smoothness, resaw capacity, and table size and strength of a big saw that make them so nice.
