Well, the pic I have isn't great, and I did go ahead and buy the battle damaged NX-01 off Ebay, and I am sure if I mentioned prices most here would say I over paid. I will take individual pics later. I have these boxed still, though, so I don't have a complete review to give of the build quality. For the most part I happen to be pleased, especially considering I couldn't paint as well myself. But the Enterprise D bridge has a glob of paint on the top that covers up the mold detail. Other than that, they look good to me, from what I can see.
I haven't found anything stating Diamond Select has any plans for an Enterprise-C, however.
