I have a nice Piper Geronimo Apache. 160 hp, so it's pretty slow. But it's about the cheapest twin you can buy and operate. I've got 70K into mine and it's probably worth about 45K. Some of the mods help the single engine performance. I've been able to hold 8K on one engine with half fuel and two people. The thing is built like a tank, old skool, and it's heavy. That's why it's not a great performer. It would be a great plane for timebuilding.
