Lastly being an early adopter is never a good thing it's better to wait for a better version with all the bug fixed from the previous model.
Absolutely agree. I regret getting the DS when it first came out.
I think you should try to sell your stuff in your own town. I do it once a month and usually pull off 200 dollars cash and that is without my job.
If you are looking for a job try to get your family to pay you first (For stuff like washing the car, etc) but if that doesn't work out try putting fliers around the place so people can see. If you are well recognized it may work out well.
If you're not old enough to work an actual job, I'd say you're either going to have to do yardwork like there's no tomorrow or wait a little longer after it comes out.
