There was a Yoga 700 (14" FHD display) at the Lenovo Outlet for $580-ish yesterday. i5 Skylake, 8GB RAM, 256GB SSD, and even a dedicated graphics card. I was really tempted to pull the trigger. It might be overkill for your needs, but it was a very good price.
Edited to add: it's not there anymore, but I would keep checking there.
