Whey concentrate is the cheapest and normally the tastiest, but it also contains lactose, which causes many people problems.
Not whey (but still protein) are casein and soy protein. I wouldn't bother with these, as they are not as anabolic as whey (though they may have a use to some).
Many protein powders contain a blend of these different types, so check the ingredient lists (the ingredients on any label are listed from most to least abundant, by mass).
And avoid questionable brands or ones with a price that seems too good to be true, as they may not even meet label claims.
Also, if you're looking for something that will have a thicker consistency, the real pure isolates or hydrolisates with very few ingredients will generally be water-thin. Read reviews and do your research, or ask the sales person if they seem knowledgable.
IMO, anything by Gaspari or Optimum Nutrition is good. Avoid the stuff with the flashy labels and huge ingredient lists with crazy claims of 8000% more muscle.
