I've seen a few prints show up on eBay but don't believe they were "marketed" well. If you want to pursue that route, see the link for a Yahoo artists forum. http://groups.yahoo.com/group/eBayArtistsNetwork/ The Digital Art Prints here haven't done well either (due to inadequate marketing IMO). And although not stictly 3d, this guy at the top link that does digital art seems to be doing well. Bottom line: you'll have to not only be good but also an aggressive marketer.
