Unless you are doing very heavy weights regularly, no amount of protein is going to make you 'bulky'. It just isn't that easy for women. It has taken me a long time to 'out-gun' most men, and I have done many years of twice daily heavy resistance training. Trust me, you will not bulk up without very good reason to.
Protein powders are all much of a like. Most health food stores tend to stock them and, I find, have plenty of information available on each individual one in store. Personally, I like Lamberts Pea Protein- which is quite simply dried peas. It has more protein per weight than a lot of powders, and tastes good stirred into most dishes, as well as with just milk.
