what is a good healthy protein powder that's not too expensive?

for the longest while ive been using orgain protein powder since that's the cheapest my mom could get and it has like vanilla and chocolate but i hate how it's gritty and chunky no matter how much you blend it taste like chalk. is there any other like protein powder that taste good? i need one that's healthy and doesn't have artificial stuff in it. not those mass gainers and serious mass protein powder. also should i get creatine?
