Comet was one of my favorite games from when I was a kid. For a while, I shrugged off owning one because it didn't have multiball, but eventually I kept seeing it and was reminded of what an absolutely beautiful machine it is. I picked up a beater early this year and did a full job on it - basically everything just short of swapping the playfield, which fortunately was mylared. It's surprising how fun this game is - there are actually a lot of rules once you start paying attention to what does what. I hope to keep this machine for many years to come, as I enjoy admiring it as much as I do playing it.
Here are some pics of how mine came out:
