I wanted a DX902 but I couldn't find any and as I said earlier I was lucky to find the XE9305. That was maybe 4 years ago. I'm not sure I would look for one now but then the XE93 is only one year younger so.....I have the XE9005, purchased after seeing it alongside the XE9305. Yes the XE9305 is noticeably brighter however, on the XE9305 the black bars above the picture were grey but on the XE9005 there were deep black (and still are on my set over three years down the line). So, to my aged eyes (but I accept not for others), the XE9005 is bright enough and I very much enjoy the picture from this TV. But I doubt you would be able to find one now, even second hand.
How often does this TV come up? Can't find the 58' on eBay, where else could I try?It shouldn't be that much.
Here's a recent sale: https://www.avforums.com/threads/panasonic-tx-58dx902-fald-led-4k-uhd-3d-tv.2319853/
TV prices fluctuate when new, let alone second hand. There's no fixed pricing second hand. Its what you can pay, and what they will sell for.
I've found one at £575 but it's a 3 hour trip to get it!The Q9FN by far. Its local dimming and HDR performance is better than the DX902, its younger and its only 75 more.
I thought you said previously that it was too expensive? That is why I put the DX902 at the top of the list.
Sorry the Sony is 3 hours. The Panasonic's close to me, but has the "minor banding"...I think the price you have for the Q70R is also fair, so if its closer just get that model. It will be better than what you have by far.
Of course this is all up to you, its about how much time and money you are willing to put in to getting a better TV. Compared to spending the same money new you'll be getting terrific value for money, that's for sure.
