Welcome to Flyertalk, we are glad to have you here, there are many people who know a lot more about these programs than I but US Airways is the only status I know of that you can buy outright, others can basically be bought through getting the credit cards.

IC Hotels Ambassador Status can be purchased though.

Most of the beauty of having status is earning it anyway, there are a lot of good promotions out there that will let you achieve status faster than you might think but you still have to earn it.
