+1 on SD75Ms. Hopefully we'll see straight SD70Ms before then end of this decade! I'm thinking about picking up one of the rereleased flared SD70Ms to detail though.
Considering its already been over a decade (2006) since they were last released. Two for CSX, two for SP, and an undecorated version, and from what I gather, it was a very small production run.
I'll keep hoping one day myself.
