Mine was cheap because it's an obsolete model and therefore probably no longer certified for new build commercial equipment. Box was damaged as well but relay looks in perfect condition. What I haven't seen cheap on eBay are the double-pole e-stop switches although I'm not too worried as I reckon that a n/c contact is more likely to work when it gets thumped in a hurry than n/o. While safety is important, I'm not building a machine that will be used by a numpty on piecework. But we all draw lines in different places...
