What's the retail price of the Nintendo DS + games in US?

[Beck]

I'm considering buying one, but here in Denmark the price is about $250, and the average game is $50.

I've seen them at about $105 on ebay
.
Does anybody know of a neteller merchant that sells them?

[Number27]

The DS Lite retails for $129.99 and you can usually find bundles for ~$150. I'm not sure about neteller merchants.

A follow-up question:
Will I have any compatibility problems, if I buy the console in the US, and playing games bought in Europe or Asia? Like different area codes (like PS and DVD's)?
