WORD OF WARNING!
Think very carefully about buying from Hong Kong - I can't fault the seller who was very friendly and helpful. BUT you get stung with Customs charges I had to pay almost £41 to get my DS delivered - and it took almost 4 weeks to get here.
ON A POSITIVE NOTE:
I love the fact that you can share the DS with your children - either by playing games with them or quietly sneaking the console away on your own to play your favourite games!
