I think you're not getting a lot of serious responses here because people don't want to say that they:
1. Have a lot of credit card debt.
2. Spend their kids' college funds.
3. Spend the money they originally planned to use for things like retirement, vacations, fixing the house.
4. Bail on other hobbies to sell them off and put the money into this one.
5. Spend their college loan money and live off ramen noodles.
