Zgemma boxs, if thats the box your going for (that was the price differential earlier Bigga, better box bigger price) are the budget end of the market but perform pretty well, the tuners can be a bit flakey compared to VU+ but since my duo popped last week and i didn't have the hip cash, i plumped for the H2 dual tuner (sat and cable) at a price of £50 plus pennies and i must say performs pretty well. not as many bells and whistles as my duo and the lack of any decent ram means i dont mess with the apps (though many report they are functional) since firesticks and plex server are much better for that.
i flashed another image to it and got it up and running with auto updates on bouquets and epg that looks similar to a well known satellite tv service provider in about 1/2 hr (and i'm a bit rusty at that)
Again sorry i cannot recommend any service providers please don't be offended
