Replacement is relatively easy, an hour or so all up. Don't know what they're worth. Mine cost $220 to rebuild I think (was when I first got the car and I didn't pay for it). Check for dirty/high resistance contacts in the plug. I have seen that several time and it would cause just the symptoms you describe. Replacing the plug would be a lot cheaper!
