i dont recommend any tv box. Get a smart google tv.
That the way forward.

I dont think so, A tv box can cost as much as SG$200 and a 32 inch tv cost slightly more with a console screen for you to watch and at the same time can be beam to your old tv and work like a box too. If future when your old tv is ready to be change to a smart tv, this small tv can be use as as a spare or can also be use as a monitor.

The only different is a smart tv dont come with the built in iptv and vod app.

However powerful it maybe. Why do people want to get tv box?
The basic reason is to watch IPTV and VOD.
So without a good iptv and vod app to serve them the box however powerful is just a box.
Now a day, their are so many device that you could watch Netflix, Disney, Amazon and many mainstream provider.
What make a different if one can watch it free from the tv box.

DIY iptv have what you want. LongTV is it android and can sideload apk into the box

Samsung smart TV i dont think is android or google tv so can only installed from their playstore
one app is Ott player which u need m3u playlist

If you do have an old PC can repurpose to be a TV box using x86 os.

Hope you can find a solution
