I wouldn't call the Nikkor SW 'not spectacular'. It's a 106-degree, 200mm IC, similar to a Fujinon SWD or Super-Angulon / Grandagon N f/5.6, they're worth around $200-500 by themselves in good nick. Plus the Nikkor is an f/4.5, bit brighter for easier focussing. (I haven't used a Nikkor, but if it's anthing like my Fujinon SWD 90, it's great).
The 210 may not be an APO or anything, but it'll almost cover 8x10, you'll never be able to shift enough to hit its limits on 4x5. Can be around $2-300 on its own.
Then add in the camera, I've never seen a nice field-cam go for much less than $500, let alone a newer model.
All up, as long as it all works, bargain.
