I really enjoy my PSC Orion. I have yet to do any blue water sailing in her though.
The boat is solid and small enough to singlehand, and its easier to finance the dream as everything is smaller and less expensive. What had finally sold me on the boats ability was the account of Brec Morgan, who solo circumnavigated his Orion out of Bloc Island. So, it can be done. The boat sails well, but it is initially a little tender. It doesn't take much to get her over to 15 degrees heel. However the boat will stay right there for some time. I've had up full sails beating in 20 to 25kt wind and the boat stayed heeled to 15-20 degrees.
It is a little small if you plan on having any good sized crew with you (wife, kids, dog)
