Amazon lists the same (new) for $350. I have pre-ordered it from MS India (Microsoftstore.co.in) for 23,000/-.
As Xbox's console's harware failure rate is high, I didn't explored the option of getting it from US. I feel it is too risky.
Anyway, with pre-order from MS India site, I am getting Dance Central game for free ($47) and a T-shirt from Puma.
Also 25% discount on Sports Active 2 (It's kind of Wii Fit with some extra accesories). It is yet to be released and is priced $97. So 25% discount on this make it very close to US price.
EDIT : Important : I think, the extra goodies (Dance Central, T-Shirt and Discount) are not available if one purchases directly from MS web site. I got this offer from MS with a unique coupen code to apply at checkout (may bcoz I am a MSDN subscriber?, not sure). So please double check about offers.
Thanks
