RIP plasma. It was the first and, for our money, it's still the best display tech out there, but with the news that Panasonic is to cut its losses and concentrate on 4k LED TVs, there are bargains to be had.

We at TechRadar don't go hunting for cheap TVs; anyone can wander around a supermarket and pick-up the latest no-brand LED TV that lasts a year or two.

No, we're only after the best-value cheap TVs around, and the current sweet-spot is the 42-inch plasma.

Take stories of plasma's demise with a massive pinch of salt. Described on TechRadar as the 'darling of home cinema' numerous times stretching back over a decade, plasma is still considered by (anyone with eyes) as the premium option for home cinema TV enthusiasts that produces a much better picture than LED. Fact.

Its drop-out status comes only from Panasonic's huge losses on plasma TV production over the last few years; no one can take away the blur-free, vibrant and contrast-heavy pictures on sets like the the Panasonic TX-P42X60B that consistently outperform LED TVs. We're destined to see new plasmas in 2014 from Panasonic, but that will likely be that.

Our advice? Grab a plasma while you can. Though the Panasonic TX-P42X60B is selling (out) at places like Currys for a mere £299, we spotted Richer Sounds putting this fine HD-ready telly out to tender at just £279.

That's for walk-in customers only, however, but it's a remarkable price for one of the most reliable 42-inch TVs around that will – judging by Panasonic's heritage in plasmas – outperform and outlast LED TVs thrice the price.
