So I heard and Edge III is a direct swap for an OFR, is this true? If so, can I just pick up and OFR at any ordinary Guitar Center, etc (mind me, I'm 16 and parents don't approve of using their money, even mine on stuff like this =[)?

I have an RG320DXQM I got from a friend, and the Edge III makes me want to slit wrists. I'm a broke New Yorker as well =[
