All the later Humax freesat records have the same functionality as each other. They run on the same firmware. The latest version running this is the HDR-1100S.
The HDR-1100S is more locked down than the Foxsat.
Arris are the next manufacturers partners for freesat. The last announcement that a saw, was that Arris recorders would be available in 2019. With nothing since mentioned that I can find I'm doubting that date. Arris should be able to provide a far more modern experience if you can wait, (and obviously check any real reviews of using the recorder, once Arris freesat recorders are available).
