If " Self flown" Think of 206L-2 LongRanger, AS 350 Astar or perhaps a AS355 Twinstar if "overwater" is a consideration. Easy to fly - not too complicated - various models available for not "too" much money.
If money is no object the field is open - a call to marketing depts of various manufactures should produce flights in all helicopters you are interested in.
I vote S-92 - if money is really no object.
