What brands/models of collapsable shovels do you guys use?

I have a BCA Traverse shovel for these reasons:
It's light

It has a somewhat smaller blade (Better, I feel, for handling heavy "cement snow" and digging inside snow caves and Quinzees)

It has a metal blade for "cement snow" caused by avalanches. I don't think plastic can pierce avy snow well enough.
