looking for ~42" flatscreen tv - full HD, 100hz+ used is okay. 3d optional

I bought the 51" samsung from myer for 799 the other day, but have since sold it because the 60hz just wasn't doing it for me. Now I'm looking for something slightly smaller. I've scouted ozbargain for the past few weeks and nothing has come up, so this is more an interest check on anyone willing to sell second hand.

I'm located in Randwick, Sydney.

If this is the wrong part of the forum to be posting on, I apologise, and feel free to delete this thread :)

Thanks.
