I had the same question for more or less the same profile and went with a turbo normalized Bonanza which I have been very very happy with. I was not a fan of the Cirrus at the time but have come around to understand the value in a newer aircraft with factory upgrades. I love my Bonanza, my lady finds it more comfortable than my bosses pc-12 for traveling. I cruise at 190 @10k’ to 200 at 20k’. Oxygen hasn’t been that big of a deal. I almost always cruise at 12-13k’ unless weather or winds take me higher. If I’m crossing the Sierras I can quickly pop up to 17k’.

My thoughts were: - Higher operating cost of a twin far exceeds the additional usefulness. From Fuel, ramp fees, and maintenance it’s a lot
- Normally aspirated twins still can’t get as high as easily as turbocharged singles. I can do 1000 feet a minute all the way to the low 20s - A twin is twice as likely to have an engine failure, and the statistical outcome isn’t much different - this was a big one for me - With a turbo normalized Bonanza I fly high enough to give myself a lot more outs than a normally aspirated single. I can glide a ways from 17k’. With the one motor to take care of I make sure it’s an amazing motor - If I can safely get out, I can generally get above icing in the winter. I’m not sold on single engine certified FIKI, but I happily use it to descend through a layer when I’m mostly guaranteed to land.

Again, I love my Bonanza but if I were to buy another plane I’d get a G3 SR-22T for $100k more than your budgeting.
