003, is the BDR-S03J OEM or retail with the box?
Personally, even if I have the money, I wouldn't buy it for $530 + 40 shipping! I would rather get locally from newegg for $229 shipped or $239+shipping for retail. Other places might be cheaper as well.
The dust proof is a marketing gimmick in my opinion. You will get dust no matter what, from the disc or when you open the tray. I would rather spend the $300 difference (wow) on good Blu-ray media, or something else.
Another thing is, manufacturer usually launch product every year, next year they will release new product and that means this product will get slower support (read: firmware upgrade). With new blu-ray media keep coming we need regular firmware upgrades otherwise it's just like my old panasonic sw-5582 can't burn newer blu-ray media and I know even the year old ggw-h10n can't burn ritek bd-r/re media correctly due to lack of firmware support.
Also you won't get warranty support since you're outside Japan. What happen if your drive broke in less than a year?
Hope this doesn't discourage you.
