C4 pan

I am looking for an aluminum C4 transmission pan. I have checked out Jegs and Summit Racing - their prices are reasonable ($80-100), but i am wondering if there is something out there i am missing. I am also curious about the "fit". i suppose some pans fit better than others.....so does anyone have any suggestions? LEAKY PANS SUCK!
 
Just wondering...why aluminum? I know its lighter and might dissipate heat a little better.

But you could do that with a deeper pan which allows you to run more fluid.

I built my own :)
