A FireStick and the built in browser (Silk) have worked fine for me all season. There's also running the iFollow app on your TV directly, but this depends how modern your TV is as to whether is supports loading of apps. If you've a modern TV that runs Android as its native OS, you may be able to load the iFollow app by sideloading the apk file*. Laptop with a cable is probably the cheapest option though (assuming you have a laptop).
*Not tried this, no idea if this works, but the APK (app file for Android) is downloadable from many places. It might also be in the Google Play store to download in the normal way, but I don't have an Android based TV so can't check.
