Everything negative you described about a drysuit can easily be rectified by proper fit, maybe some ankle weights and practice. At your level of experience, I'm sure you'll have a drysuit mastered after very few dives.
As for PSD, it's a locally variable thing. In the Brainerd area, for instance,they need more PSD divers. They have a hard time getting enough people together for their practice dives. They have great equipment,too - a result of 9/11 funding. In the Twin Cities, I've ice dived with the Scott Co sheriff dept. and I think they only have law enforcement officers on their team. The city of Bloomington has an all volunteer FD, and they have a dive team with excellent equipment. One way or another, I'm sure you could ID a local PSD opportunity because they come in so many flavors.
