Thanks for your comments Bethany. I too am not sure all the fuss about plastic is worth the effort and expense it takes to convert. I've been doing it a little bit at a time. When K-Mart has a sale on Pyrex I'll get some and replace the plastic here and there. I do like how easy it is to take Pyrex out of the freezer and put it in the microwave. Now that is something plastic can't do!
