Mark, I've never purchased from KEH before. Between he two optins here, http://www.keh.com/camera/Canon-EOS-...99089813R?r=FE, which would you recommend? The distinction between the LN and EX+ seems so minor would the extra $50 even be worth it?

I have another week to return the used Sigma I purchased from Amazon, thats why I'm picking everyones brain so much this weekend.
