Dufour sailboats in the 50'' plus - info wanted.

[Myblueheaven]

I am interested in comments on the following boats that include build quality, known problems, owner comments, things i should know as a potential buyer.

I am in the market for a sailboat with lines like the Jeanneau 51 or Beneteau Oceanis, but came across a couple of Dual Cockpit boats, a Dufour model( maybe a few) and the Gib Sea 52, early 90''s era. I have since attempted to find info like reviews and owner comments on these but to little avail. I really like the dual cockpit layout as it seems to have the best of both worlds - rear helm but a nice seating area for guest. Any other boats in the configuration I can learn about in the 49 to 57 ft. range would be great.
