Ha ha....I'm the thread starter and have decided to bring it back from the dead!
Sooooo.... I finally updated the breakers in my main panel. Well, I had an electrician do it. I needed to swap out about 4 wide breakers with GE thinline ones, moved those, replace a 60a split panel breaker with 80a, and installed the 30a dual breaker. Took him about 1.5 hours and cost $220.
Lessons learned. Did he do anything differently? Not really. Most of the effort was just busy work of running wire into the panel, routing it, replacing breakers. But part of that price is peace of mind knowing everything is ok in the panel. With all the wiring things are packed in pretty tight.
If there was an empty spot that needed a new breaker to be dropped in I wouldn't think twice about doing so in the future.
