Where is the best place to buy Minix Neo U1? I saw sellers are selling in Lazada, Lelong, and others. Not looking solely at price but also continual after sales support

I used to own a WD Media Player and I am a happy customer. I later bought Skybox thinking watching cheap AXtro is fine but I went in with big surprise - the watching experience is unbearable with frame cut / turn black every 10 secs. Image is blurry. I now watch official Astro using NJOI decoder paying RM21/month (a good deal by their customer service for me to test watch all nearly all channels including HD for 3 months)

Because there are too many of Android box in the market, to find a good gem is hard now. I'm new to Andoid players. Can other Minix user attest to this, especially this Neo U1 model?

I want to be on the safe side, buy only good quality product that can last
