In that case, I recommend against getting a large set of bakeware in favor of getting a few open stock pieces at a time. You'll pay a little more overall, but you won't have items you never use; you'll only get what you need at the time. For instance, the little bitty Pyrex glass bowls with the lids that come in the large set. I never used them, they were the wrong size for everything, and they make lousy mixing bowls because the sides are straight. Sure you can use them to store leftovers in the fridge, but you can use Gladware for that purpose, too, and Gladware travels to work for lunch purposes way easier than glass bowls. I ended up taking them to Goodwill.
You know, you might check at Goodwill, see what they have! It's not like Corningware or Pyrex goes bad or anything...if it's unbroken, it's useable, after all.
