How about an early Bonanza? I paid $27,000 for my 54 E35 in 1996 and
it is worth about $45,000 today. I go a good 10 knt faster than my
friend's Arrow at lower fuel flow. I flight plan 145 knt @ 10.5 gph,
and it true out at 150 on most days. Parts are more expensive but you
don't need them as often. It is harder to find A/P who knows about
Conti E225 engines but they are out there.

Whatever you buy, do a prepurchase by an A/P who knows the type. If
you need to pay more for a "specialist" to do prebuy, it is still worth
it!
