Balanced XLR cables

I am purchasing a preamp with balanced xlr connections.  some of my other gear has xlr terminals but never used them for lack of source input until now with the preamp.  is there a big difference in xlr's?  not trying to start a cable war discussion, just dont want to spend an arm / leg. is $50 for a 3 ft cable on the cheap side?  i havr always found Mogami cables good value.  recommendations please
