I bought and installed a new garage door opener as a gift. I also purchased (but have not yet installed) a couple of fluorescent fixtures to replace the bare 100W bulbs.
Having now completed the work, I can state with authority that I would rather be unemployed and hungry than be a drywall installer.
Below are two pictures taken of the garage before we started the work.
Below are pictures I took of our handiwork afterwards. Fortunately it was "just a garage", so the finished look wasn't too much of an issue.
I added an access hatch to the garage attic, although I wasn't sure that it was necessary.
The garage door opener is a belt-drive type. It is unbelievably quiet!
Below is a video comparing chain and belt drives. I think I will be installing these in my own garage pretty soon :)
