Protein powder - opinions?

I'm a vegetarian, and I know I'm not getting enough protein. What are your opinions about protein powders, do you reccommend any, and do you think it would be unhealthy to work these into my diet everyday?

i used soy protein powder when I was vegan.  If you veggie then you have the whey option still.  I heard its better but I am not sure why LOL  I still have a ton of soy I need to eat so I am sticking with it :)
