As seen here, we're not too far from Star Wars-quality prosthetics, and better ones soon after. Sure it isn't made of durasteel, but it will enable fine control. Although I can't immediately find a reference of Anakin's hand containing sensory feedback systems (though he could clench his hand so hard that the electronic feedback would make his shoulder ache, per the RoTS novel, he didn't have "pain sensors"), the new bionic hands will have that capability.
Further, the hands will (like early-model Terminators) feature a false covering designed to mimic human flesh. In other words, no need for a black glove to cover up shiny metal.
Of course this will all cost some coin, and probably won't be readily available for a decade or more. I'd imagine also that some sort of power system is required, though presumably the same is true of Anakin's hand (given Vader's many systems). Given our power tech I'm sure there will be need of recharging. However, that's hardly a vast improvement.
Of course, a few decades after this becomes available, I'd bet that instead of all this bionics we'd rather simply use cloned body parts. You don't have to create a complete lifeform, after all . . . cell differentiation is what makes organs and pieces to begin with. Replicating that will take a bit more effort than just growing a whole new human being, but it won't be impossible. However, Star Wars seems not to possess that technology for some reason, which is quite odd given the cloning elsewhere.
Of course Trek is no exception to this oddity, what with Picard's bionic heart and Nog's "biosynthetic" leg. I'm not even sure what a biosynthetic leg is, exactly, but it sounds like instead of cloned Nog-parts they used either a forced-growth setup (a la the new arm of Swamp Thing from the movie of the same name), or attached something which adapted itself to Nog's leg requirements, or else some sort of android-like leg composed largely of biomaterial and not all artificial bits like Data, or something else altogether. Nog was gone to a starbase for a time to get the procedure done, though, so it apparently isn't as fast a job as Luke's hand seemed to be.
However, since Anakin's hand presumably had all the time in the world to get installed, it seems that limb replacement is generally more advanced in Trek, whereas Star Wars limb replacement in the Republic era topped out at a level of tech comparable to mid-21st Century Earth.
