EZNeo ATSC Tuner?

Thought this was an interesting ATSC tuner : http://www.dtvusaforum.com/ebay-con...verter-box-ezneo-td-100-hdtv-atsc-tunner.html

This box can't be compared with those box sale on Radio Shack,BestBuy ect,ect,ect. Why?

Ezneo is a true High defintion Converter box supporting 480i-480p-720p- & 1080i converter box sold on radio shack,bestbuy are not real High Def, they

are only Digital connected true RCA Video cable or Coaxial,. Ezneo has real components R/G/B & DVI
