twice, but only because I royally f'd it up the first time.
-2004 my brother bought a 46" hitachi RPTV (crt). it was phenomenal, and to this day one of the top tvs I've ever laid eyes on. at the time he lived at home, a couple years later he moved out and left the tv, and I kind of inherited it.
-2010 I decided it was finally time to get a 'flat panel' since crt was no longer available and the hitachi wasn't calibrating as perfectly as it used to. grabbed a Samsung pn50B530, which is one of the worst TV's I've ever owned...
-2013 after years of trying to justify replacing a fully working tv, the hitachi(that I moved into the living room) completely died. I moved the b530 into the living room and bought a Samsung 64F8500. after making the mistake of thinking newer was automatically better when I bought the b530, I told myself I was only going to look at the best. for me it was a toss up between the f8500, vt60, and zt60, and I opted for the f8500 because it was immediately available, several hundred dollars cheaper(over a thousand cheaper than zt60), and in the store I preferred the look of the f8500 over the vt60 slightly.
I don't like to buy TV's for no reason. I don't get rid of them until they break normally. I'm quite certain the tv that will replace the f8500 will be an oled, and likely not for several years. most of the TV's in the house now are less than 5yrs old, which means none of them are 'on their last legs'. that and, I don't want to replace TV's with anything I find 'worse', and in all honesty, I HATE what is out there in the market right now. I actually prefer the dynex ccfl lcd(my oldest, and lowest quality tv) to the edgelit led's on the market right now.
