The DS is definitely a great system to have and it has a lot of great games on it. Personally for me, it's my 2nd most played system, which goes in this order for playing time 360>DS>3DS>Wii>PSP (just started playing this again, bought Persona 2: IS)>>>>>PS3 (only used for movies as there are no ps3 games I want to play)
As for what DS you should get.The DS Lite is great if you want to play to play GBA games as well. If you don't care about them and still want a portable system, then the DSi is nice as it has a slightly larger screen and it's still very portable. If you want a big screen then the DSi XL is great, but not as portable as the others. The 3DS can also play DS games, but I still prefer using my DS over my 3DS for DS games.
