Roku or streaming device tv (East New york)

I was just blessed with a TV I am picking up tomorrow and really need a Roku or streaming device for it to make it a smart tv to use it because I do not have cable tv service but I have home internet and with such a device I would be able to use the TV for free. Please if anyone has anything I don't care whatever it it is at all as long as it works . I appreciate your help and God Bless
