MLS-12D, that was the most sensibly written article I have seen for a long time about the pro's and con's of a/c ownership.
I've owned for 8 years now and have never regretted it, and I am by no means rich!
The benefits of ownership (as mentioned in the article) are all very real and if anyone out there is wondering whether they should go for it or not just make sure you buy something "normal" such as a Piper or Cessna and I guarantee you will not lose money on it. If you show it some TLC you will actually make money, I have done on 3 a/c now.
Think of it as an investment like a house, thats the kind of appreciation you might well see if you're lucky.
