I can vouch for solotripper's oven, it worked well, baked quickly and gave our yeast bread a nice crust.  [smiley=thumbup.gif]
I use a bakepacker on solo trips, it is lighter to carry than a reflector oven and less bother to cook with.  However your product does not have a crust which some people might miss and I haven't been successfull in making brownies in it (too gooey).  It does make excellent muffins, biscuits, quick breads and cakes.
I have a large reflector oven which I take on trips with several campers.  We can then enjoy yeast breads and rolls, brownies, cookies and cobblers.  :)
