Thanks for all your input, folks.  In the end I've decided to go with the Swedish reflector oven for a number of reasons.  If I'm on the move I don't see myself doing much baking.  However, if I'm moving at a more leisurely pace which is more typical, with layovers then I really want to be baking over an open fire.  Reflector ovens seem ideal for that.  The Swedish one is pretty light weight at about a pound and a half and folds up to take almost no room in the pack plus there is a distributor right in my neck of the woods.  Anyway, I'll let you all know how it works out when we get back from Wabakimi in September.  Yes!!
