what I really want is something that doesn't take up much room.

Depending on your needs, you might look at this another way.  Our cook kit has a large pot, a medium pot, and a small pot (none collapsible).  What we take from the kit depends on the number of people and length of the trip.  Regardless of what we take, everything packs inside of the largest object.  That includes (depending on what we bring), cups, bowls, silverware, utensils, sponge/scrubby, stove, firestarter, etc.

No matter how much volume the largest pot in the cook kit takes up, if you pack its insides with other stuff, the total space that everything takes up in your pack is no more than if the pot was collapsible (and you had to pack the other stuff outside the pot).
