Yes, absolutely worth it! I bought one on 30th November, it has the other color, which is combination of darker(than this grey) black plus silvery white bottom panel area. There are a lot of options, single button to switch between outputs, and tv. Picture is clear and great as well, although not as good and lively as compared to my old 1996(i think so) made in japan Sony with trinitron picture tube(same tube in this one too). But I didn't felt comfort with the sound, it's clear and there's an equalizer with some presets present, but it gives you feeling of being overrun, like headache, but that might be because it's kept in a smaaaalll room.
I got a local deal from Sony World at around Rs. 10,500, so you can probably bargain a bit more. We searched around at LG showrooms and Samsung too, but this one was bought at first sight. I didn't find any other Sony in this range to compete this one.
If you need a 21'' CRT this is my best choice so far.
This is 5th Sony CRT 21'' Monitor in our family, the first being from the 1980s decade. Hehehe. And the one you are mentioning is living happy life at my village
