Looking for recommendations for a cheap 55in tv

My searching ability sucks and couldn't find anything specific so here goes. I'm looking for a 55in (or so) 4k TV. I don't really want to spend much on it. So I'd like to know what the absolute basement price would be for something that isn't complete garbage.

On Amazon, I see the Omni TVs are around 450 CAD but on here, it seems that everyone is against them. On paper they'd fit my needs (basically 100% for streaming tv shows).
