Well I'm gonna play the devil's advocate.
If I were you I would save for a 3DS. DS games are going to begin disapearing this winter and developers are already drawing down support. The 3DS is fully backwards compatable with the DS and you will be able to play Black/White Silver/Gold on it as well.
Now If your saying that your tight on cash and can't afford to save for a 3DS. My next peice of advice would be to hold off a year. As I said above 3DS will begin to take over and DS will begin to draw down. If sales for 3DS don't improve I'm guessing Nintendo will do more to phase out DS so that people buy 3DS instead. I'd expect a price cut within a year if not sooner. Also software will become extremely cheap over the next few years as DS phades away.
But if you have to have a handheld now I'd say 3DS is your best shot. If you have to have one now and can't afford 3DS then I'd suggest buying a DS:Lite and instead of Gold or Silver I would get Black or White vastly superior games and they also offer a fresh and new experiance!
