I recommend glass. I like Anchor Hocking, Libbey (Target or the Container Store), IKEA 365 has some glass containers I like and Crate and Barrel does, too. The most expensive one I bought was a large casserole dish from Anchor Hocking--I think it was $10. The Ball canning jars are great, too! (I've bought them by the case(?) at a grocery store).
