Should I pick up an FS5II in perfect condition for $2000?

I already have an FX3, and an FS700 with 4K raw upgrade, but neither of them are very ergonomic for run and gun shooting outdoors. The FX-3 puts out an amazing image, and for low light is a no brainer. But with no viewfinder and no built in ND it takes some rigging and you are going to have to deal with the no EVH issue in full sun. Full frame 4k up to 120 fps with no crop covers just about anything.

The FS700 also puts out an amazing image - in plenty of light, that is. Shooting interviews on sticks, it is gold. Got old school NDs, but they are damn convenient. But outdoors you are stuck dealing with the atomos recorder/monitor that you need to get 4k raw, for every single shoot and it is not particularly ergonomic or run and gun friendly.

This FS5ii just felt so good in the hand. Viewfinder right there to look down into. Electronic NDs. Talk me out of it. Or into it.

How good - or bad - is the image out of this? How are the internal 4k recordings? Color science? preamps? Any glaring issues?

If I got it, I guess I would just sell off my full FS700 kit, Atomos Ninja SDI and all.

Thanks!

EDIT: Thanks everyone, for all the solid advice. Basically you guys were mostly reinforcing my own internal voice of reason - the only logical upgrade for me is the FX6.
