Pawn Shop. Help me!!!! ( Games and stuff )

[Battler Ushiromiya]

Ok I want to buy a hand held....
I want it cheap......
I prolly need to go to a pawn shop for this.....
What hand Held should I get, DS, or PSP?
What price should I look for? (I hope it is under $80.)
When I buy it what should i do to make sure it works 100% and nothing is wrong with it?

Anything else you can add would be nice!

Edit: And yes I did give my own thread 5 stars to make it stick out! :P
