the 300 hp Cherokee 6 would be the better choice out of the above. Fixed gear, less MX costs and room to grow.
True, but then the original post said "inexpensive", and the 260 hp Sixes are $20-40K cheaper than a 300 hp. And they make a good 4 place + bags. In fact, they don't run much more than a Dakota, if any.
Then we all found out "inexpensive" meant $110K or so, that is the low-average price for a decent 182RG. And if you're willing to pay $100k for an airplane, plus pay the insurance premium for a 100 hr Private Pilot to fly one, why the heck would you worry about the difference between 11 gph and 13 gph???? 200 hrs per year X 2gph X $3/gal = about 1/4 his annual insurance premium.
Heck, save yourself $20k on the price of a 182RG and buy a Commanche 250-260...
