The box matters too though. If you're wanting exact sly-like setup, the closest is E2 boxes such as Zgemma and so on. You can then load most lPTV services on there, but there is a bit of setup required. In my opinion, that's the best route given your reasonable budget.
Alternatively, something like a firestick with a decent app. Again, my own preference is to avoid the "smarters" rebranded apps.
