acehole

Consider an Inogen oxygen concentrator. These portable units are good into the high teens and preclude the expensive, awkward and arcane traditional oxygen tank systems. You will save huge amounts over time just avoiding the expensive O2 refills, even if you fly with a small backup tank. See recent Av.Consumer discussion.

Will it haul 700lbs. for 700nm @70% power(with ifr reserves)? Careful comparing Mooney's & Bo's...

I owned a'65 C model for 7yrs in the 80's(978#Useful load)- fast(148kias),efficient,cramped(esp.lumbar area after 2hr),ok for hauling small kids in the rear,but really only for 2adults.Impressive handling in a level 3 TSRA.Mission changed after kids grew. I owned a Cessna twin for the next 6yr, then owned an A36 Bonanza for 15 yr (ULwas ~1330#;106gal). Beech parts costs are much higher, tho things like bladder replacement require much less labor than redoing a wet wing.Cross country travel at 165ktas & 800nm for up to four adults in the Beech was sheer luxury.CG not a problem if common sense is used. Considering all factors(hanger,insurance,annual/unexpected maint.,panel upgrades,STC's,fuel/oil) yearly expenses for each plane (including the twin) averaged about 3-4 times the hourly fuel costs(excluding engine overhaul).This was for flying ~100 hr/year. Never budget one of these babies on a monthly basis, and keep a big cash reserve ready for surprise AD's, engine, panel & fuselage "glitches". MY ADVICE TO ANY PROSPECTIVE OWNER: CAREFULLY REVIEW ENGINE,PROP,AND AIRFRAME LOGS FOR THE PAST 5 YEARS(get work orders if poss.),and estimate the hourly costs& parts prices involved.(A mechanic can help you do this to help separate fact from fantasy).Most owners never do this simple but valuable prepurchase move.
