Frankly, it's sad to read a pilot writing something like that. Let me suggest an three hour option that will allow you to arrive in style and relaxed...
Figure your making at least a buck and a quarter from Delta. Don't know if they are paying you for mileage, but 26 hours of windshield time between Delta trips must just suck for you and your family.
Speaking of family, trips to the beach are "currency." Besides, you need the tax write off.
Mine's an A36 now, but the F33 or 33-35 is a better machine unless you need the extra capability. I had a 33-35 with a fresh IO-550 by D'Shannon and all the go fast goodies that I sold when Delta hired me ... wish very badly I still had it. Best flying airplane ever built IMHO (and that includes the 757, heresey I know)
Plan B if you have no kids. Go for the parallel valve Lycoming powered M20C through J models. They're all good and very reliable. M20J - "205" or late as you can afford "201" since quality improved as time went on.
The six cylinder Mooney's never made much sense to me. At that point they perform much like a Bonanza, but just aren't nearly as comfortable and you're giving up 757 control coordination.
The tupperware airplanes are, again, a bit slower and thirstier than the Bonanzas. Some say they are comfortable, but the build quality of the early ones annoy me and the newer ones are very expensive. Most morons run the IO-500's hot on the ramp while playing with the avionics reducing the life of everything under the cowling. Cirrus needs an APU install for their customer base.
