@shilbert: Aww bud, thanks!
@Storm: Thanks! I'm a big fan of the built-in retopo tools (as seen in part 1) and prefer it over topogun and especially zbrush. Blend_Ideas has written an incredible tool called
Bsurfaces that is particularly useful for retopology (
demo). It also depends on what you're coming from. If modo 601 is your tool of choice, Blender's modeling/retopology tool-set might not seem as up-to-date. If you're coming from maya, Blender has its modeling/retopo tool-set beat easy imo.
