So having read posts in the forum to see if I can recover my Solo2 (stopped at UBIFS update) , it looks most probable its beyond economic repair.

I have therefore trawled the forum for various recommendations. In my (wife's) budget are probably;

AX HD61
Zgemma H7S
Vu+ Zero 4k just realised only 1 tuner.

I (still have a VU Zero for my 1080p projector) and my family Solo2 was setup with twin tuners to a Technomate motorised 1.2M dish, OpenVix with Slyk UI. I hope to slavage the 500MB HD and will check its a 2.5" that can be transferred over as it has some family video I'm keen to retain.

I currently don't have 4k capable TV but the last of the great 1080P Panasonic plasmas ~8 years old so may only have a few years left and I have recently replaced my surround sound with a 4K capable Marrantz AV so anticipating a 4K panel in the nearish future will be a necessity

Apart from the price.... what are some factors I should consider whene deciding between the two?

Cheers
