Prior to re-joining the Air Force, I was in the Auto trade for 5 years, and as others have said, you don't NEED to get the rotors skimmed every brake pad change. Unless there is a noticable lip or gouges in the disc, I wouldn't worry.
The only thing is, if you or your partner intend on replacing the brake pads yourselves to save money, put that saved money towards a decent set of pads, not cheap and nasty $40 ones.
And give the pads a quick scuff with some medium grit sandpaper before you put them in. You don't need to go to town on them, just a very brief rough up. Then once in, bed them in properly. ie drive down the road and brake heavily (but don't stop), and do that a few times in succession.
Buy a brake piston spreader too, they are only $10 from Repco. They make life REALLY easy when putting the pads in!
