Also, feel free to share details about any plane you are considering buying, you'll get a whole host of responses.
Being a novice to aircraft ownership, it would help to have someone mentor you along the way, and be sure to have a thorough pre-buy inspection on anything you are considering. Many planes that look good actually have serious issues, and conversely, some "dogs" that you'd shy away from can be quite solid and can be a better bargain especially if a seller is motivated to sell, and it only needs some cosmetic work for example. Actually, now is a good time to buy, as the market is soft, and prices are lower as a result of the economy.
