+1 on no smaller than 17" wheels. That gives you the capability to run carbide tipped blades like the Lenox TriMaster which is a game changer for resawing. A 17" saw really doesn't have a larger footprint if space is a concern and the additional throat depth never hurts. IMO any of the Grizzly 0513 series are a great value if you are not a brand snob (we have 2 in a college shop and have never had problems with them).
