Interestingly, I have bought two sets from this box a couple of years ago; the minotaurs and the centaurs. Those were of a suitable size to work as actual minotaurs and dragon ogres (with some conversion work). The plastic is of a good, hard quality too, but obviously not as crisp or easy to work with as actual polystyrene.
Like this set, they were dirt cheap (but not as cheap as yours

) and quite nice figures overall, especially for the price. I also bought a set of orks, which I intend to use as trolls eventually.
For the money spent, I'd not fret too much; even if you only use one as a terain piece, you'll already have recovered the cost of the entire box
