The Roku express is Roku's entry level streaming stick that is very similar to NOW TV, in fact Roku & NOW TV are partly owned by Sky and as such they are both good entries into the Sky ecosystem.
The Roku express stick has everything that NOW TV comes with, in addition it includes some apps that you probably don't want to miss out on, including Netflix, Google play & Amazon prime videos.
So bonus points to Roku here. Overall the Roku express is a very good entry level streaming device, it has more apps than NOW TV and is more customisable.
Television with available HDMI input, Internet connection via Wi-Fi (5+ Mbps) and a power socket.
