Well if you encounter the dreaded nib wobble, send it to Cross and they will replace it with a new Century II. Not the same pen, but you won't have to throw it out. Their life time warranty goes a long way.
My first classic century was completely clogged with dried ink. It was listed in ebay as new, but I think it sat in a drawer for a couple of decades with the original cartridge left in it with the ink turned to powder. It took almost a week of soaking in an ammonia/water bath before I was able to unclog it. It is now a wet smooth writer. I've had it for some 5 years so far and no nib wobble.
