Nikon D3 vs. D3s

[dele]

Morning,

I'm in the market for a new SLR body to replace the venerable D2X I used to have, I cant justify going mental and getting a D4/D4s so I'm looking to go used again and found that there's quite a disparity between the D3 and D3s prices

I guess I'm asking if anyone here can confirm if a used D3s is worth twice as much as a used D3? as a wildcard, I've also noticed the D750 is within budget (Not really interested in a D800 as I've owned one already)

Thanks all

Ended up getting a D3, it just feels so right in the hands
