How badly is your phone's screen cracked?
If its a small non-intrusive mark then don't even think about getting it fixed/replaced.
Now, if its broken to the point the screen is unusable and beyond repair then go get yourself a new phone.
Now I would recommend getting another Apple phone but this time try taking some extra precautions when handling it.
Get yourself a good protective case and screen protectors.
I myself have had my iPhone 5c since last winter and it's in pretty good condition with minimal marking and no cracks.
