What 911 to Buy with $60K

I am just about ready to buy myself a Porsche. I have about 60K set aside for the purchase and I'd like a 911 so there are a few options for me. I have seen examples of all three of these under 60K, some well under like the 40th Anniversary which I am starting to see often in the mid 40K range.

1. 04 40th Anniversary
2. 05 C2S
3. 02-03 Turbo

What's going to be the better car for a newbie? Am I missing anything is there a model I should be looking at and am not? Better yet can some suggest a reason NOT to buy any of these and at least I may be able to whittle down my search a bit!

Thanks Mike
