For 10k you can easily get a 19" WS lcd from any brand of your like. But stay away from viewsonic, read that it has very bad aftersale service. Also make sure that the lcd has DVI input, don't buy a lcd which doesn't have DVI.
And as for how safe is lcd, what do you mean by it?
Advantage of lcd:
Low power consumption (less electricity bills)
Doesn't strain your eyes.
Light weight (easy to move around)
Very small footprint (more desk space)
Looks are way better than CRT
