Should I buy a TiVo Stream?

Here's the setup.

We have a TiVo Premiere 2-tuner, with lifetime and a Comcast cablecard. It is in the living room.

We recently re-did the kitchen, and we'd prefer not to have a cable box or any cable access there. We're using an LCD monitor with a TiVo Fire TV (box, not stick), and it has been working well. We're not thrilled about not being able to watch live cable, but I sideloaded the XFinity Go app, and it works, sorta.

I saw that the TiVo app is in beta, and it would supposedly allow us to stream content from our Premiere to the Amazon Fire TV. But the Premiere 2-tuner is not supported as a streaming device.

It would appear that a TiVo Stream would solve this problem for us. I think it would also add the ability to stream to any devices, etc., but that's not the concern. We just want to be able to watch the recorded TiVo shows in the kitchen without actually moving the TiVo from the living room to the kitchen.

The only other thing I've tried is to pull the shows using Archivo and then serving them up via Plex. This is inconvenient and slow.

So... worth the $129? Will it solve the problem/issue? Other options to consider?

Thanks for the advice.
