This item has been discontinued by the manufacturer and is no longer available.

Acer Aspire TimelineX AS5830TG-6402 15.6" LX.RHQ02.021 B&H

Tigerdirect never got back to me, but here's B&H's responce:
Thank you for contacting the E-Mail Sales Department at B&H Photo Video and Pro Audio.

I'm sorry, but I do not have any information regarding why Acer discontinued that model.
It could be that they finally realized that they are idiots and made a 540m version for the US.
