Just picked up a PS50B450 Samsung 50" plasma TV at Domayne Alexandria for $1649 with $250 HN gift voucher thrown in, making the end price value $1399.
That's the ticketed price - I went the interest free route (the current 850 days interest free deal ends this weekend) so it wasn't negotiated any lower, but if you are paying cash it could go down a bit. Not sure when the deal expires, but definitely a good price IMHO for those who are looking for an excellent quality non-full-HD panel (and no, I'm not going to get into the whole full-HD v non-full-HD debate…) - it's basically either this one or the Panasonic 50X10A at this price range.
Service was friendly there too, have bought a few things from there and the service was consistently better than the pretty poor service at the Alexandria and Moore Park HNs, but I digress…
Good luck!
EDIT - by HN vouchers, I meant $250 of vouchers (gift cards actually, they just gave me the ones that someone who give me if they bought it as a gift) that can be used at Harvey Norman, Domayne or Joyce Mayne (as set out on the back of my gift cards anyway).
HN voucher?
