DS lite should be costing abt $200+ ba . Sorry this
question i can't give a good answer but when it comes to modding
hehe . Well one thing good abt NDS lite is that you don't have to
mod it like psp . You just have a buy a card for example , R4 or
Super card , to load in the software that comes with the " cards "
into the can't rem is micro or mini sd cards , then you can load in
all the Nds lite pirated games into it to play . The R4 can also
play mp3 and video like the psp although the resolution is not as
good as psp . And the best part is you don't have to void your nds
lite warranty just to play pirated games . Cos the R4 only have to
insert into the cartridge slot for the nds game . Generally nds
games usually largest size is only 128mb nia while generally most
of the games are just 64mb which means you really can put abt at
least 10 games into the memory card assuming 1GB and be pampered
for choice . Go here for more details abt it . http://r4ds.cn/
. As to where to buy ... this you have to find yourself cos
after the police raid in sim lim , many of them either not selling
anymore or selling at sky high prices . It used to sell at $40
during the initial launch but i bought it for $54 after a few
months , the last time i ask was abt $80 , so good luck to you
.
