I would agree with the recommendations, both amp-wise and tool wise. My Hakko 936 is still going on its original tips. The ratshack tips ruin themselves
As for amps, my brother has one of the beta torpedos that I built for him and uses it with his T50RPs, as well as AKG K501s and what's the Russian phone, Fischer Audio or something like that? It does fine with all of them.
I personally prefer my Dynalo with my T50RPs, but that is probably outside the scope of your build capabilities at this point, and part sourcing would be painful.
