If it's the rod tip only, it is easy to replace those yourself. They sell the glue and rod tips at Academy.
Just gently heat the existing tip with a lighter and pull the old tip off with a pair of pliers (careful it is hot). heat the glue stick with the lighter to melt it a little and dab the glue on the end of the rod. Select the appropriate diameter (there are three or four common sizes)and slide it on the tip. Again with pliers as the glue is hot. Make sure it is lined up correctly. Trip excess glue. There you have it a new tip. Other guides are more complicated.
