Last year I wrote a cheap Apple hardware guide for people who wanted to use this service while it was only on iOS and AppleTV. On AndroidTV I have been using the Onn streaming devices as reference hardware to test with. These devices are generally well reviewed and got for $14 for a stick and $19 for the box. This is probably the least expensive way to use this service. I regularly test with the box and have heard from others that the stick, which is hardware wise similar works fine as well.
