I tend to notice out of balance wheels more at higher speeds, but it could be something as simple and cheap as a wheel balance, especially if you live in a pothole ridden area or frequently drive through one.
And if it is your rotors you can always have them turned if they aren't in bad shape (and if it's actually cost effective) while you spend some deciding what better than OEM rotor you decide you want replace them with.
I personally wouldn't drive on turned rotors unless I really needed to though, with the lost mass they'll be more prone to warping and cracking because of the thinner disc. And depending on how much you get charged to turn them it may just be just better off to replace them in one shot instead of throwing money at something you'll be throwing out eventually anyway.
If it is the rotors check/have the pads checked to make sure that: A)they didn't cause the damage to the rotors in the first place, and that B)they're in in decent shape and will be up to the task of stopping the car once the new rotors go on. In either case, replace them.
Powerslot is a good lower priced option for new rotors, used them on my 240SX for years and was always happy. They've got a cryo-treated treated rotor that is supposed to be more durable than their standard rotor but I don't have any firsthand experience on that. If you want to spend a little more you can get some replacement rotors from DBA (Disc Brakes Australia) and if your wallet is still too fat you can step up and buy the 4000 or 5000 series from DBA. I don't run them currently but may end up going with the 4000 series thanks to some good performance reviews from a couple of friends (non-Z) and RacingBrake's ever increasingly pricey lineup (they were my old choice).
