As a corollary to this, I am also curious about vitamin D levels in people using UV tanning beds.

Assuming equal carcinogenic potential from sun exposure and from such beds (which is most likely an incorrect assumption), the results should be insightful.

So long as they're getting exposed to UVB, they should be producing Vitamin D. E.g., http://www.nature.com/jid/journal/v125/n5/full/5603599a.html

The absolute amount of Vitamin D needed is quite modest, and the risk of cancer is (typically seen as) proportional to sun exposure; hence the recommendation for some - but not much - UV exposure.
