Just before I bought my 150 I had a chance to but into a 1/3 share of a really beefed up 172. A great ifr plane with almost all the bells and whistles on it but I'll tell you what, after just a "little bit" of thought I bought the 150,I did so because I just wasn't fond of having to ask someone if I could use "my" plane. I'd rather burden the expense of the entire plane myself than to try to get money out of people that didn't think that items needed to be fixed on the plane. Just toooooo much hastle for me. I'm glad I bought the 150.
