Exactly. If You want a reliable 3 speed hub the Sturmey Archer AW is the one to get. It basically allways works and if it doesn't it's really easy to take it apart and fix it yourself. Parts are available and not expensive. I would look for a pre 1984 model. They say those form the 50ies are the best. I'm currently running 7 of those and i'm happy.

If it has to be SRAM i would rather look for an original Sachs Torpedo model 55, 415 or 515. Those seem to be as reliable as the Sturmey Archer AW but i guess it's harder to get replacement parts (at least outside of germany).

Accodring to Sheldon Brown/John Allen the Shimano 3 speeds seem to be rather problematic. They talk about shattered pawls and subsequent destruction of the hub through the shards.
