Currently I have the pleasure to fly a T182T with a G1000, I got my cloud card in it about 2 months ago. They fly great and are a real pleasure, just the fuel bill stings a little.
Nice plane. Only $434,000 for a new one (not including tax and other costs).
http://www.cessna.com/single-engine/skylane/skylane-pricing.htmlQuestion: ever wonder what happens when the G1000 goes on the blink? There is a very interesting discussion about that on the AOPA forum. Answer is, not much you can do, short of replacing the whole thing.
In any case, good luck in selling your TNWings restored C-150. It's a beaut.
