In another thread at studentpilot.com a couple people said they'd want a turbine Bonanza if they could have any GA single. That got me thinking, a guy that comes into GED has the same Allision conversion on his P210 and a couple of pilots and I were talking about it saying that it wasn't worth 600,000. So is the conversion on the Bonanza worth it? I can't imagine you could go much farther or faster, only higher. Is there a big change in gross wieght?
