Cong ats on your purchase! Pangarap ko magka oled. Siguro pag mas affordable na
Actually, if you compare the prices of say, the mid-level Panasonic plasma sets back in 2013, the current price of the LG 55CX is either lower or the same, adjusting for inflation over the years. This means you're actually getting more for your money in terms of the sets now, kasi higher 4k resolution, Dolby Atmos, smart TV etc. Note also 2013 was probably the period where Plasma tech was the peak in terms of quality and also the lowest in price, relatively speaking.
So yes, you can wait some more, pero if you buy the 2020 models (CX/BX/GX) at current prices, they present very good value for money.
Naghintay din ako until sets became more affordable. The 55CX I recall is priced at par nominally with the Panasonic UT/ST plasma sets before.
