Opinions on Cessna 340, 414 and 421

I'm considering buying a plane, and have decided to go with a twin. I
understand that there will be more maintenance costs over a single,
but I like the safety margin of the second engine. I also like the
idea of pressurization, because we have some high mountains out here
on the west coast. It would be nice to fly over them at a safe
altitude, and I would also like to be able to get on top of most of
the weather.

I'd like to hear opinions on the 340, 414, and 421. A former commecial
pilot recommended the 340 or 414 to me. He said the 421 is good, but
has some kind of gear drive that could make maintenance more
expensive.

Also, I'd like opinions on the engine out performance and handling.
I'm told some twins are more difficult than others when an engine is
out.
