The 7.3 seems to be the best all around engine for me. I maintain my vehicles quite well, so I'm not worried about that once I own the truck, its just the previous owner that I have to worry about. Hopefully the previous owner will have taken care of the truck well.
There seems to be plenty of trucks out there, but none of the good deals are near me, they are more down south, with quite a few in texas. The only problem that I have, is that I wouldn't be able to actually take a look at the truck before I buy it. I hate to make a huge trip to look at a truck, only to not buy it.
But I have found plenty of F250's and F350's that meet my criteria (which isn't nearly as high as before). I now need to really figure out what the fuel mileage will be on one, so I make sure that I will be happy with it.
