I am going to be buying a Canon 100mm macro lens and have a bit of a dilemma regarding how to go about it. Here are my buying options:
1. Buy a used one from another person for $415 (includes a hood and filter)
or
2. Purchase a refurbished one for $499 (includes 1yr warranty)
Should I just go ahead and spend the extra $80 so that I have the warranty? the only drawback would be I still have to pick up a hood (but I think they are only a couple bucks on ebay)
Decisions, decisions
