As a policy I think it is foolish to buy things that you do not need and cannot afford.
I suppose if there was reason to believe a ban was imminent and you would kick your self for the rest of yout life if you didn't own one and you were willing to pay thousands more for it by taking out a loan then it might be worth it to you.
I would not ever finance one or a similar toy. Short of a house if I cannot afford it then I dont buy it.
If you enjoy it and can afford to finance it then enjoy yourself and have a good time.
I dont consider being able to make the payments as being able to afford it. While toaday you might be able to make those payments you dont own a crystal ball and there is no guarantee that you will be able to continue to do so, particualarly given the current financial climate.
You don't need other people's opinions on how you spend your money, for fun or otherwise
A loan isn't YOUR money its the bank's (or the loaning party's). It is your money that will pay off the interest however. True you dont need anyone elses advice but that is not to say heeding it may not be the prudent thing to do. The thousands upon thousands of forclosures that are out there right now are good evidence of that point.
I would adise that if you really want one you examine your current expenses, find where you can save, people are often shocked to learn how much money they spend on certain habits such as eating out, smoking, going to the bar, etc. Start saving what you can and when you have $8k saved up if you still want one get it. Also if you have an emergency in the mean time you wont be nearly as screwed. Rember 8K< 13K or whatever financing it will cost you in the end.
My dad always told me there are two kinds of people in the world. Those making interest and those paying it. I greatly prefer being in the first group. The beauty or horror of interest is it never stops working.
