Amazon seems to have pulled the plug on its Kindle DX.
A peek at the product's Web site shows that Amazon is no longer directly selling the DX. Only used versions are up for grabs from third-party resellers, at prices ranging from $230 to $350.
The DX also is missing from the Kindle family lineup. The e-book reader's heave-ho comes about a week after Amazon cut its price to $299 from $379, according to blog site The eBook Reader.
There's no indication from Amazon as to whether new supplies are on their way. But it's unlikely. The current DX is already more than two years old, and no refresh was mentioned last month when new models were unveiled.
CNET contacted Amazon for comment and will update the story when we receive more information.
Amazon now lists four Kindle e-readers in its lineup: the $69 Kindle, the $139 Kindle with 3G and keyboard, the $119 Kindle Paperwhite, and the $179 Kindle Paperwhite with 3G.
The retailer's tablet lineup features the $159 Kindle Fire, the $199 Kindle Fire HD, the $299 8.9-inch Kindle Fire HD, and the $499 8.9-inch Kindle Fire HD 8.9 with 4G.
