you've pretty much mentioned them all.
samsung will have the f5300, h5000, or f8500
LG still might have a couple on the shelves, but i've been far less impressed with them.
imo, the f8500 is the only long term worthy purchase. the others are cheap enough though, that if you only plan to use them for 2-3yrs until oled [hopefully] becomes affordable, it still makes sense.
i hate to say it, but you have definitely waited too long. 2013 was the best year for buying a plasma. there was at least one great model at every price range. nothing new(really) has come out since
