just spotted a Rapoo wireless keyboard today at flipkart for 500/-. they have Rapoo wireless mouse 1620G for 500/- too. have used the latter. it was good.
otherwise, there're 1-2 combos of Logitech W/L KB+mouse on flipkart. i have used Logitech K270 W/L keyboard (with Dell WM123 W/L mouse) with my TV (Pana 50VT20D) earlier. no hiccups experienced.
