Welcome to the forums.

Tough call on 60's vs. 80's. I could not decide so am investing the $60 return shipping to be able to listen to both in my HT. Other than that, one year old is hard to go wrong with ,assuming they are in very good condition. $700 is 30% of list and 21% off the factory outlet price. If you offer a bit less, it could be a no brainer. Good luck
