Dented Radiator

My radiator got dented this weekend but is not leaking at all. I did a search on radiator repair and found a good place but wanted to know how I could tell if I really need to have it fixed.

The dent is on the left side of the radiator and looks like the bike fell over on a baseball :( .

I was planning on jut keeping an eye on it and see if it starts leaking then get it fixed.

Any thoughts.
