I know a couple of people from the UK that just dive in a good 7mm wetsuit/farmerjohn getup. However, they are considering moving to dry. I personally dive dry; did the wesuit thing for awhile until I had enough money for a "semi-dry" (read leaking drysuit) and saved a few more pennies and finally bought a Viking. The temps around here are a crisp 34-68 depending on location, time of year, and weather patterns, and they swing during the "season" as well.
I would strongly recommend a drysuit, a good quality shell suit works well. Neoprene is an alright choice if its crushed neoprene (less to no compression at depth than regular neoprene) and it may hold up to the rigors of wreck diving better, but I do have any data to that account since I've been doing wrecks in a shell suit for years and have had no complications.
As far as a learning curve, sure there is that. Is it for newbies? Sure. Many courses offer that in the regular open water course due to location. Up in Alaska they utilize drysuits in their entry level courses (according to an article in Rodale's or was it Skin Diver?). They teach the buoyancy sections using the drysuit as well as the BC (for those times when you don't need a drysuit). Its a pretty easy thing to learn if you've been using them through the course. However, if that has not been the case, then I would recommend doing your OW dives wet then move on to a course that deals specifically with a drysuit because there are some additional skills and knowledge necessary to use them.
Cheers
