Well since all of the great 3D product domains are gone, adding "cheap" in front seems like the best move.
I can't think of a better word to add to these 3D product domains (new, sales, online....)
Not sure what would be best for "search results", You'd have to research.
Here's a quick recent domain sales list for "cheap"
