There's no such thing as a cheap 310 if you intend to fly it. The cost of the airplane should be your last consideration. Condition, history, etc can save you much more than initial purchase price. If hours are what you want, pick up a used Comanche twin. At least the fuel cost is going to be less. If you do, though, fly your approach at 80 and don't cut the power, then you can get a smoothe landing 30% of the time.
