The price differential is compelling, if they are in fact the exact same item ($254 after the $28 shipping, $248 if you get the shipping insurance). The only drawback: Hong Kong.
The warranty is a plus, but if there is something wrong with it, you'll have to ship it back to Hong Kong for at least $28. You'll also have to pay to ship it back, so it will be at least $56, plus whatever time it is out of service for.
Someone else posted about this recently. Search on terms "digitalww" and you'll find a thread about a big price differential.
