BD has an opinion, just like you and everybody else. The "life support" line is used often, it comes in many different flavors. Personally I wouldn't buy a used reg. Everyone here is more than entitled to buy a used reg. It is unlikely that I would buy a used reg. Nor would I buy a reg for $1400. I don't have to have a reason that makes sense to anyone but me. It's my money, not yours.
I have read this entire thread. It went from a discussion about gear and progressed to a list of personal insults and accusations. Neither side won. It won't change what I buy or where I buy it.
