I really think they're cheap because they're such an oddity. The use an oddball caliber, sights are in schritt instead of meters, they use an en-bloc clip, straight pull (and not smooth like the Swiss actions), and they will bruise your shoulder in short order. Add in a ton of them available, and you end up with a cheap rifle. The bores do vary, but accuracy is typically better than Mosin Nagants.
