Actually hor vincent09, you've been wondering very long whether to get it or not, if I'm you (meaning have the ability to get a DS Lite), I would have bought a DS Lite long ago. I understand that you're concern on the price of DS Lite, if you get cheated or what not. It's just like my feelings when I was trying to get a new handphone few months ago; I ended up getting it from my parents' friend, though the phone wasn't the latest firmware & etc. but at least I know it's reliable (cause my parents know him). Though I was a bit worried initially, but I know if anything goes wrong I can just bring it back to the uncle and he'll help me settle it.
Personally, I do not know DjiNn above here, but I've read many posts and many LYN forumers also recommend DjiNn here. SO it means he is reliable and actually done many businesses with LYN forumers. What I'm trying to say is I wouldn't mind spending some extra cash to buy the DS Lite from DjiNn, at least you know he is reliable and trusted by many forumers here. And I believe the forumers here (including myself) are not associated with DjiNn or whatsoever, I myself have not purchased anything from DjiNn, it's just posts I read here that convinced me he is a responsible seller. SO, I have no means in advertising for DjiNn, it's just my thoughts.
NOW. GO get your DS Lite already XD I want one so badly for Pokemon Diamond/Pearl, Animal Crossing, Harvest Moon DS, Spectrobes, Ouendan..........the list goes on

But YOU, you have the opportunity to get one, so don't hesitate anymore. JUST GO GET A DAMM DS LITE LOLZ If you get conned/cheated/conned/cheated or conned or cheated

just treat it as a lesson lorr!
GOOD LUCK~! vincent09
