The tupperware thread

I decided the Kitchen needed a thread on tupperware. Yes. The kitchen lives up to it's new name, and I surrender.

I was wondering if anybody knows a tupperware container brand that doesn't melt in the microwave. I tried some cheap Dixie and Ziploc brand tupperware containers, and they both failed pretty fast and easy. I suppose I could resort to some Rubbermaid, but I like the disposability of the cheaper stuff in case something spoils inside, and... essentially becomes part of the container. Any advice?

Besides that, how much do you rely on tupperware? I use them for fresh herbs & spices, but beyond that, I try to avoid them altogether. It isn't like I resent them, but the only time it seems I use them is to bring some leftovers for lunch to work.

Jam it back in, in the dark.
