I moved over to TabloTV about 8 or 9 years ago. I got tied of fixing stuff when I would update something and Tablo just worked on the Roku without much fuss.
I’m still happy with and love the Tablo, but it’s no better than MythTV was, just easier to maintain.
If you’re thinking of something like $1-2/month, also consider doing a 30 dollar 1 time thing (it saves on transaction fees) and you basically just paid for 2-3 years of donations.
