CRT is better than allof'em.
Had 2007 model of Panasonic Viera 42" plazma. Nice picture although not too many adjustment options. Consumes 4...5x more energy than CRT! Recently the digital board blew off. Part itself worth more than remaining value of TV. Tried to pitch it $225 to Pawn America hoping that after the break would turn back on for 5m, didn't happen darn! Destined to stay in basement full of dust and spider web.
Modern LCDs or LEDs don't promise any reliability in the future only to be disposable entities no matter how much you're paying for'em. So my advise don't buy'em used eva 'n stretch for the warranty plan because they will FUBAR.
Found on CL used Sony 32" full HD CRT $80 and this unit has superior quality than any of flat screens mentioned and will ever be made LED LCD or plazma. The only downside is limited size. The largest flat screen CRT ever been manufactured is only 34".
Plan to buy more of them:-) in case your flats will break or you'd like to see a better picture, drop me a note and I'll resell these units $250 firm.
