Just wait another year or two, 4K will be even cheaper
How expensive are they where you're from. I'm from Chicago and I bought my 50-ish inch (I want to say 55, but I'm really not sure) for around $300 almost a year ago. They seem to have already reached the point where they are sold for very cheap. If a few years go by and Leynos still hasn't gotten one, maybe wait for 8k, I would think.
