I recently picked up a used Vision + from a local guy thru eBay.
Never crashed and it came with 3 batteries and a nice hard case....I gave him $650 for it.
Yep, batteries alone go for $99.00 current market. Plug into the assistant and then go to the battery tab. Check each battery for number of charges it has been through. Be sure you do a fiull IMU calibration, RC stick cal and befor flight a compass calibration. If you didn't get the manual go th DJI and download it. Tons of informations.
