I emailed the seller and this is what he had to say:

Regardless of the price, you don't ever want to cross-drill AND slot a set of rotors. One or the other, but not both. All it does is weaken the rotor, without providing any additional benefit.
For a car which will never be taken to the track, cross-drilled rotors are fine. They give you improved bite, reduced delay of braking in wet conditions, and you save up to 1/4 pound per rotor over plain or slotted. For track use, you should go with slotted. Under race conditions, drilled rotors will crack sooner than plain or slotted rotors. Slotted give you virtually the same improvement in initial bite as drilled, without the propensity to crack under tough conditions.
Getting back to this vendor - you might want to ask him where these rotors are manufactured. I suspect they are cast in Mainland China or Taiwan. There are a handful of decent foundries in Asia, but most of them are boutique foundries with dirt floors, no process control, no adherence to standards of quality, and they crank out total junk. For example, I've seen casting flash completely block airflow through some cheap Asian rotors. If he says they are made at in ISO certified foundry in Asia, ask him the name of it. If it really is a quality foundry, he won't be afraid to identify it by name.
