Probably find something about it in the CECB section
Nope, I've done searches and this is the only thread where it appears. The pictures and price do make it seem very similar to a CECB but AFAIK it is not coupon eligible. The written specifications that don't seem to match the pictures (component, coaxial digital, S/PDIF outputs) clearly would disqualify it and make it sound like a low-end HDTV box.
It does appear to be a CECB box since there is apparentrly an error in the description of the box in the link.
At the top of the link it says Component output but at the more detailed description near the bottom of the link it says Composite instead.
