thanks to everyone for the help on considering a 310. it fits the mission statement that i have laid out. but now i am weighing a 310 vs a 340. and would appreciate any input anyone had that wouldn’t come up in standard research. thanks
I would take the 310 over a 340.
Unless you have specific need for the pressurized cabin I would stay away from the extra cost. Nothing wrong with the 340, it is a good airframe but given the choice and no real pressing need for it I would get an unpressurized aircraft.
thanks for the input that is how i am leaning. but perhaps there are some unseen benefits to the 340 if anyone has some?
Four engines instead of two 
when did they c340 get four engines? im sure there is some humor here but being as dense as i am i am not picking up on it
You never mentioned ‘C’ in your original post; I assumed ‘A’.

Must be a quiet day in the office! 
well indeed that would make a big difference. if only i could afford an a 340.
I bought a 340 2 1/2 years ago.
Love it.
I tire kicked 310’s, but along came a deal for a 340 I couldn’t turn down.
Insurance is going to be higher than a 310. All you need to tell an insurance agent is “pressurized” and they cringe.
My first year premium was $15k, but in addition…I had to attend a week at FlightSafety…$5k, plus expenses.
Second year premium…$10k, and FlightSafety recurrent training (every other year) drops to $3k.
Hopefully, this upcoming year will drop a little more again.
Realize too, that I didn’t have any ME time when I bought it, so that didn’t help me either.
I like the pressurization. In the winter months, it gets me up above 90% of the wx around here where the rocks are tall, yet during the summer months when the thunderstorms are high, I can stay down low beneath them and performance doesn’t suffer much.
I have RAM VI’s, flight plan for 215kts @ 18-19,000, but if I want to pour fuel through the engines, she’ll do 225+ kts @20-22,000.
RAM engines, American Aviation intercoolers and vortex generators are very important…they make Cessna’s numbers legit.
Costs are $2,500/month for it to just to sit in a hangar.
Double that price if you fly it a decent amount of time per year.
Annual expenses=$10-15k
Insurance (see above)
Hangar (around here)=$7k
