Do not buy the cheapest, you'll regret that when putting it down.
Also choose the one which can be assembled without adhesive.
This is my opinion of laminates, I usually do plastic vinyl or cork floorings or ceramic tiles etc.
I made my bedroom's floor with 'clic' laminate, there has not been any problems with it. Of course it feels a little bit colder than real wooden floors, but it can resist the damage caused by falling objects much better.
