Thinking of Buying a 337

[Testpile]

I have always been a big fan of the 337, even though I have never flown in one. I'm finally to the point where I think I can afford and have enough experience to move up. I got my multi in a seneca and have about 12 hrs. total m.e. I have about 275 hrs total. What kind of yearly costs am I looking at. Do I have enough time to get reasonable insurance. What else do I need to know. I have a wife and four kids, they enjoy flying with me and we think this would be a good family plane. Any advice would be appreciated.
