Hello fellow junkies!

Since I stumbled over Ilvy some years ago, I'm intrigued. Since I sailed her once (thanks to Paul) I'm infected.
For several reasons I'd start with a pocket cruiser (if I really ever take the plunge ), something around 20 feet. Can you please share your experiences with such boats as the Newbridge Navigator, the Kingfisher 20+ JR or the Coromandel (or other comparable boats I have not noticed yet)?
All of them would be affordable and somehow available. In fact I don't need a twin keeled boat in the Baltic, but I'm looking for a simple solution. I don't plan on converting a boat like Paul did - just converting friends and students to this incredibly simple way of sailing. 
Which boat would you consider more satisfying in its sailing performance?
Thanks a lot in advance, looking forward to hearing (reading) about some first hand experiences!

Fair winds and happy returns to everyone

Heiko
