Thanks Gents
The Twin Comanche is the only viable option for the specific requirements, i.e. two engines and (relatively speaking!) acceptable cost. No need for blistering speed, massive load capacity or fancy avionics.
Interesting tip that, the fuel selectors I mean. Must have gotten your undivided attention when one started spluttering. Had a similar thing happen to me in a 310 once, mind you that was self-inflicted.
