Lixada 650ml titanium pot, BRS 3000 stove, and Toaks long handled titanium spoon. About $50 total, and you won't find a lighter wt. option (just a hair over 4 oz.), and still be able to fit everything into the pot (except the spoon), along with a 100g fuel canister.

I've been using this system (mine has the 650ml Toaks pot), for several years now and have been very happy with it.
