Question Where to buy original lcd+digitizer for gt-i9300 black (in US)?

Hi! My wife broke her screen on her GT-I9300 black.

I'm looking to buy a new one (lcd + digitizer).

There're a lot of offers on ebay & amazon but I want to be sure it's original & etc. Anyone already bought it? Please share the link!

! I need one that fits exactly GT-I9300, not US S3s (not att not verizon not sprint not tmobile!!!)

Also I'd prefer some local US seller as we're here.

Thanks!

P.S. hate Samsung! Why can't they deliver their parts globally? I bought this phone in Germany & it was broken in US & they officially refuse to help us!
