I have the LG 60PS60 and love it. I previously had a Samsung plasma, and was tempted to get another, but the LG still looks great and had a better price. I think Samsung has the best picture out there, and the LG was close. The only thing the LG cannot do as well is whites do not show as bright, they are a little more faded.
As mentioned, $1700 isnt too great of a price. Between the sales, cashback, price adjustments, and a mistake on Sears end, I wound up getting it for about $1050. Keep an eye out for the deals and you just might get one.
