I am looking at Lake Buccaneers (and possibly Seabees) for purchase. It would be an occasional toy for me (after I get my rating) and possibly leased to a school for training in. Obviously I will get a thorough pre-buy by someone who knows what he's looking at, but what do I really need to know before buying one of these? Anything in particular I should look out for? I've noticed that on the Lakes, there seem to be a lot of various options and accessories. Any I should seek out or avoid?
