I know I'm coming really late to this thread, but here goes.
I'm not at all a fan of Turtledove. He's a Byzantine Empire historian writing althistory of the US, and it really shows. He makes mistakes a first year grad student couldn't get away with.
I agree with the Spinrad recommendation. Its very twisted, sometimes horrific, but very well written.
Roth is also a great writer as well.
Mack Reynolds did a book with a time traveling anthropologist who helps Aztecs defeat Cortez simply by providing a few warnings.
And if you're interested in reading history, the What If? series are quite good.
