Need an new driveshaft made. Who do you use?

I was going to go with Denny's Driveshaft, but it looks like they have a 3-4 week lead time.
I am going from a 904 to a 1330 (9" don't shoot me). I'm thinking just a heavy duty 3" shaft, no nitrous or trans brake and only making about 420 hp maybe. Who do you use? Cost? Thanks.
