I'm buying the 70-300 L this week
The store has an unsold new copy of the lens from 2010 ( serial no. 72xxxxxxxx) which they will let me have at the old price but with full normal warranty from date of my purchase. It's a small but significant saving. I've tested the lens thoroughly and it's absolutely fresh, new and working perfectly.
Do I buy this lens or should I just opt for a recently manufactured copy?
