Just scored a R(efurbished)IB w/referb Gimbal directly from 3DR with parts warranty for $225 (includes shipping). It arrived today and as expected there is no sign it ever came out of the box. I haven't popped the cover but suspect its RevB. The battery was out of the last batch manufactured 11/15.
These are still available from 3DR. They are also selling NIB Solo for $150+ shipping and refurbed Gimbals for $100+ shipping.
