Looking at saving for one of these. I have a Hisense H506250A that I got for £299 when I got my PS4 Pro on the same day (so had to cheap out a bit). I have been considering a C9 as it seems to tick all the right boxes and also looking ahead for next gen consoles. I have a One X and PS4 Pro already.
Depending on price, I can get a B9 for £1098 which is just over my preferred budget of £1000. I can wait for black friday so just food for thought atm.
given C9 and B9 have stopped being produced a while back with introduction of 2020 models, would not bank on the 2019 models being available until then given they are already a fair bit cheaper then the 2020 range. Just something to keep in mind. That said, even if the 2019 models are gone by then, spray see drop in price for Black Friday for 2020 models.
