House - Knob and Tube Wiring

Is this really happening, do I get to delete something from my house repair to-do list? Why yes, yes I do.
We have a light that I wrote about that we supposedly repaired. Well, we didn't. It still shot the bulbs out of the socket like little glass jets. I had it with whatever electrical mess was going on upstairs and had money in the savings account so called the handy dandy electrician. My kids sleep up there, and I am not fretting about possible snafus in the wiring system that could be dangerous. The electrical co. is the same who rewired the main part of the house and put in a new electrical box. When I talked to the 'bidder guy' who comes out to quote a job, he told me that they just did a house like ours with knob and tube and it was $8K. That is NOT how much I had in the savings account. So we talked a bit, and he said he could send my original two electricians out, Greg and Jim for $700 a day and they could figure out what was going on. Greg and Jim came out yesterday and when they were leaving at 3:30 they said "We replaced all the knob and tube and questionable outlets and fixtures." So the price to upgrade the upstairs went from $8000 to $700. I gave them cheesecake and a loaf of fresh bread. I think that worked out in my favor.
