Go with Sharp, local & old tv technician advised me that in arena of all Chaina assembled product, with CRT TV, sharp still giving best though sharp to china made.
I prefer 21" over 29".... go & watch live at showroom & than only decide.
For good sound I still prefer Videocon Bazooka & Oniaa 21" Black with Sub-woofer (both is old model but New with same features may be in market... go & search)
