I also vote for the 10M. If you haven't already, check out Dan Pfeiffer's site
www.pearsoninfo.net. Dan currently owns a 10M and his site details all the projects he has done to it, or has underway. The yard manager at my marina also has one and has sailed it up and down the east coast. You'll enjoy the extra room the 33 footer has.
Full disclosure -- I own a P-33-2.
