Flight Times

I really don't know anything about flying, and at times am terrified on
a commercial airliner (something about turbulence...)

Anyway, I do enjoy flight sims and would like to work through the
FS2004 training and then move onto X-Plane. I know this isn't
realistic, but I will have a better understanding on how everything
works without the hairpulling.

I do have question about flying to Vegas from Phoenix. How long will
that take with a Cessna single engine? How much does it cost to rent a
plane for that kind of trip (rough estimate)?

Thanks.
