mP,
Robert M Price has lost a lot of credibility with his mythiscism amongst scholars. He is a minority in the academic world with his radical theories. I have read some of his work and heard his debates but if you ever get a chance, there's a radio show called 'Unbelievable' where Ehrman absolutely destroys Price's arguments relating to the historical Jesus.
Also, the verses transhuman68 just quoted are all before the end of Mark 16:8. Of course everything after those verses were added.
