To the original poster: look for bikes that have tall headtubes for a given size (Specialized Roubaix comes to mind). That way, you will have a better chance of getting the reach right without an excessive amount of saddle to handlebar drop.
+1 Felt Z series, Cannondale Synapse, Trek 1.X & 2.X all have taller headtubes/shorter top tubes than their racier counterparts.
