Help! Reach is coming out soon!

[Shadow1336]

As most of you know, Halo Reach comes out the 14th. I, as a hardcore halo fan, have preordered the Limited Edition Halo edition Xbox 360. And at 400 dollars, I had a lot of money to earn. I was off to a good start when I found a $100 dollar bill. I immediatly put it torward reach.
$100 dollars down.
Then, I decided to sell an old laptop of mine. It was one of these. That got me $135.
$235 dollars closer to reach.
Now, with reach less than thirty days, I have nearly exhausted all of my options. Sadly, I cannot get a job. Its far too late for that, anyways.
So, I'm looking for opinions. I have a DS that I could trade in or sell, and I'm wondering if anybody knows how much It'll go for.
Any and all advice is appreciated.

A DS would probably go for 10$ over 50 bucks depending on the model and condition. Go check around eBay and see what used ones are going for, because at GameStop you'll get less than 20 dollars. You can sell in your Xbox(assuming you have one) since you'll be getting a new one anyways.

I'm keeping my old xBox.
And, at gamestop, a DS will only go for $30. I just checked.
