WE have a chopper from PC that I really like. It was a gift. The chopped re-indexes as you push on it so it chops veggies very finely very quickly. Very quick and easy to disassemble and clean. Without it, there are certain recipes I just flat out wouldn't take the time to make - - too much fine chopping involved. One example is lettuce wraps.
oh, we also have a PC veggie steamer. It was a gift as well.
It's a black plastic container, the lid has holes in it. You put in veggies, put some water, and put it in the microwave.
It does a great job, is so quick & easy to clean.
That said, I really hate the idea of cooking things in the microwave in plastic, so I often go the traditional steaming route on the stove.
