Protein powders?

Hi everyone, know I'm not here much.  But I'm going to try to lose weight again by building muscle/burning fat. <---- idea  Do you think that would work?

Lots of body builders use whey protein shakes.  they have some in the gym I go to and they are amazing.  I had one for breakfast this morning after a workout.  Calories to protein ratio is really low.

Does anyone know any good protein powders other than Whey?  I'm looking to become more vegan so it's a bit against that to go for whey protein ... though I'm tempted.
