is the Arcadia review. There are only about 20 in the states. The attalia which is considered a 32' boat is very similar as mentioned, but much more findable, as is the Sunshine. ALL three models have fin and CB versions. Sundream, Sun light are some newer versions of these. Older jeanneau's are worth taking a peak at.
For me if you look at a Beneteau, look at some of the first series versions. These are nice interior wise, but have some speed and are ment to be raced then cruised, or cruised very fast. Most unfortunately for you, will be deeper keels. I have not heard that shoal keels are needed as much on the GL's as they are on the east coast in salt water. I would not personally rule one out if you can. If frieghters are moving about on the lakes with 15-20' drafts, a 5-7' draft sailboat should not have issues! or to me, at least no more than a 3-5' draft one! But that is coming from someone that sails in 300-600+ feet of water here in Puget Sound, shoal draft boats are a liability to sell vs deep draft boats!
As mentioned by the fellow with the Pearson, they are good boats. I know another fellow that has had one for many years, and know who sold it to him. 20 yrs tween them and it is still moving. BUT< the recent owner mentioned yesterday he has an offer or is close to do so on a C310! I think that one will be a bit nicer for him and spouse since they are close to retiring!
I would also suggest a boat if possible with in your budget newer than about 82, you will not have the pinched transoms from the late 70's IOR heyday. WHile upwind great boats, down wind, they can get tricky. That is a me personal opinion...not that it is worth much.
