Check feedback and reassure yourself with contact about the seller. If something still feels funny then - trust the feeling and walk away.
That having been said, you can usually get brand new stuff for 15-20% off MSRP new in store and 20-30% off if you find the right source, so look at the $600 off and figure if the % is actually high. Almost nobody goes over about 30% new unless there is a reason (no dealer in West coast for example, the company may sell direct at substantial discount).
Good luck,
Jacob
