I joined on a Falcon 2000 although I had plenty of hours for command. I was pleased at the time because its a nice aircraft with a F/A and a nice life. However, you won't upgrade on a large cabin so it will delay your move to a LHS slot by as much as a year - which is a big financial penalty. So if you have the hours to go for an upgrade straight away your better getting a small or medium cabin aircraft. Funnily enough I actually enjoyed it more operating the smaller aircraft.
