Well, cybernetics wasn't supposed to be a MAJOR part of Star Wars, just as aside due to the number of Glowy Sticks Of Death that get used and thus the loss of a limb is going to happen every now and then.
So there was a rule to allow replacement ones, but at a cost. And, thus, you don't fight Jedi with a blaster.
You fight them with many blasters. And laser cannons. Orbital bombardment is the best suggestion.
That said, our group was old and experienced enough that we DID defeat a Force User with a blaster once. Thing is, it was our Jedi buddy that was slowly going insane due to a Sith artifact that was embedded in his skin. We set for stun, and just kept him asleep for the rest of the trip. "If he moves, shoot him again." "OK." "On stun, Crunch, STUN." "That the blue one on the switch, right?" "Yes Crunch. The one you never use." "OK. I use it now. If I can move switch, it seem stuck." "Yeah, I get that too."
