With all of the talk and comparisons about the digital converter boxes,which one seems to be the best to go with at this time?I have two of the coupons that I got for my parents use.They don't pay attention to all of the digital talk about the conversion coming and I want to get two good boxes for them.I will install and set everything up for them.Basically just wanting opinions about which box to go with.The coupons expire 5/29/08.
