We have been using Sony Trinitron 21" TV since many years and it has been a good viewing experience for us.
The picture quality is nice and comes with various options / settings for custom viewing.
Sound quality is also good and delivers clear audio for reception to our ears.
Have faced a couple of minor issues after may be 5-7 years of usage which got solved by the electrician with nominal cost, but that is nothing in front of the numerous years of quality experience.
In conclusion, it is worth the money to purchase this or any TV by Sony.
