I don't believe that the house is knob and tube, I could be wrong, but none of the outlets and light fixtures I've been into appear to be knob and tubing, all the wiring is run together, not separated.
Its not so much a question of the cost of outlets, but seeing as how I'm a little bit OCD, I'm annoyed at the fact that there are 2 GFCI's wasting space where they're not necessary. I do know that all the outlets are on the same circuit because they all turn off when the circuit is shut off, I don't know necessarily how the wiring goes, if they're all wired into the same chain or not.
Basically it sounds like the consensus is its not worth the hassle to change them all out?
