That all depends on what you do with your car. If you're really into performance driving / racing / track days, you'll want a different brand than somebody who uses theirs as a weekend cruiser; and you may want to reconsider the cross-drilled requirement if you do track the car. They tend to crack easier when put under that kind of stress.
Anyway, a good place to start looking would be at Baer Decelarotors, which are a good balance between performance and price, especially if you buy them here: (about $120 cheaper than anywhere else I've seen them, AND a supporting vendor)
If you want more performance but at a higher price, then check out Baer's Eradispeed rotors. They are still cross-drilled and slotted as well.
If you're more into looks and less into performance, you don't necessarily need to splurge on high-end parts. For example, I went with a set of 4 rotors from Brake Performance, that ran all of $260 shipped. I have 500 miles on my set as of today, and I am very pleased with them.
