There is black and white for local sets too, in fact all colours
are available for export and local sets. But if you are getting
those limited edition sets, like the Brain Age 2 Crimson / Black
set etc, there is only export sets
The only diff in local and export sets are the warranty, which is 3
months provide for Maxsoft. Export sets are are only $10 cheaper to
local sets, so paying $10 for 3 months warranty, why not?
In fact, if you bought an export set, it will be a 2 pin charger as
most export sets come from US or Japan. If the shop is good, they
will do a 1 to 1 exchange on the charger from a 2 pin to 3 pin, at
no extra cost.
I do know a place which sell a local set with r4, 1gd micro sd,
screen protecter and casing @ less then $350. PM me if you want the
address.
Buying seperately from all over sg might be cheaper on the surface,
but by how much? The savings will be only about $20 - $30. And if
you take into the consideration of transport charges, the saving
might not be high. So you might as well get everything done at a
shop, and if you got any problems, you can look for them for help
too.
