Over the past couple of years I've purchased several seasons of a couple of shows off Amazon Instant Video. So far I've watched them using their Unbox program. However, that program is going away in a few weeks. I'm looking at getting the Amazon Fire Stick, but I don't know anyone who has one. I know a couple of people with Roku and they seem to like it. Anyone have any suggestions or opinions? I don't watch Netflix, so it would be mostly used for Amazon videos (for now at least). Thanks!
