Great Choice. I just switched from a 04 Outback Dir drive to an 06 LSV. Love it. You are getting a great deal.
Will be a great family boat. Only slow speed handling difference will be at near 0mph as the rudder is behind the prop not connected as an I/O Be patient around docks and you'll learn how to move it a round. Also, the Inboards have much better handling than I/O at cruising/towing speeds.

You did not mention wake plate.. does it have that? That will help some with the water skiing. Unless you will be running a slalom course, you'll love the LSV. The wake is not bad at slalom speed, just not tournament flat. I don't do any slalom skiing so not a prob for me!
