From which shop did you buy it for Rs 6900?. Did he have the Live?. If so how much did he quote?.
I dont know if it is a good price or not, however all I can say is that you could have got it for a lesser price had you taken the online route. I think there is the same WD TV HD on sale on this forum for Rs 5000. I need a Live, otherwise I would have gone for it.
That said, couple of months back, when I inquired for the WD TV (the version you have bought) I was quoted Rs 7700. So relatively 6900 is a better buy.
