We have been thinking of replacing our's for the past

god only knows how long!
We also have not gone flat yet

we brought a Panasonic along time ago and to be honest for how we use the TV we have not seen a replacement that offers the same or better features or picture improvement

and yes 100hz all the way.
If I was to replace tomorrow I would go with a Viera, LCD under 42' , plasma over 42'.
Was tempted by the LED samsung but probably only because its 'new tech' more than anything else, having read the Avforums review I will hold of a little longer myself.
