I bought this stove from Amazon in 2011 and this is the third summer we've used it camping.  The only differences comparing this stove to my father's from 30+ years ago is the color (his is a lighter green), the metal case is a little thinner (which isn't an issue at all...we haven't dented it in 30-40 times of use so far), and the tank doesn't let you fill it up when it is attached to the rest of the stove (which is a safety thing, and probably a wise decision).  Functionally, it lights easier that my father's (likely because the parts are much newer and cleaner) and has burned with a blue flame every time (once it took a while, but every other time it was quick and easy).  It also comes with a filter funnel that doesn't let you overfill/spill which is quite handy.
