My sister wants to drop cable and get a device for Amazon Prime video. I'm helping her out; at Christmas when I visit we'll go out and get something and connect it. Her TV is a 2006-ish Mitsubishi, 50"-60", probably DLP. I don't know if it had HDMI, but I'm assuming not for now.What's a good device for amazon prime? Any options for HD without HDMI? My best ideas so far are Roku 2 (SD only through composite video) or maybe a new blu-ray player.
