Just get slotted. They don't reduce the amount of braking surface as much as cross drilled. Cross drilled unless you are going for racing and stuff they are just for show.
Sloted only looses about 4% of its braking surface
Drilled looses about 7-15% of its braking surface
Drilled and sloted looses about 9-20% of its braking surface
Also real drilled rotors are also doweled.
Look porsche doesn't even use cross or sloted stock.
If you have to get drilled or slotted rotors, just get sloted and good pads.
