Helmet 88, a member here on Scuba Board recently advertised some Diving Concept suits for sale. They were a great price at $800 if they'll fit, although you'll need to get seals replaced. This company went out of business last spring but made excellent suits. I have one of their top of the line, trilam, custom suits and it ran nearly $3,000 with all of the extras that I added.
I would put the Diving Concepts and DUI trilam, and Santi suits in an upper category. These are very nice suits, if you find one that fits or have them custom made. I love a trilam because I dive many different water temperatures and often the topside temperatures are very warm. The trilam allows me to layer and adjust my undergarments for any water temperature from tropical to sub-freezing temps. Also, there is no change on very deep dives like there will be with neoprene dry suits.
The Fusion suit is in a category of its own.
The Hog and Edge suits are a nice priced, entry level trilam that appear to be a very good deal.
Another nice thing about trilams. If you travel. They are very,very light. They dry fast. You can travel with a trilam to a tropical or slightly cool water dive site with the same or less weight than with a wetsuit and return home with less weight because the wetsuit takes so long to dry.
In Europe, you have some nice drysuits to look at, particularly the Santi. Also, since you live in an area with lots of cold water divers, I would assume that the used market might be decent. A used drysuit isn't a bad deal and if you're handy you can learn to change seals yourself or have the rings installed to be able to do quick changes of seals as needed, which is a really great feature.
Take a drysuit class and see what your shop or club has to offer. You may find a great deal on a used or last year's model on dale.
