The Galileo is hanging on my tree right now! My mom bought it for me in 1992 and it is one of the only ornaments I put up. I leave the rest of that to the kids. I am not very festive...
We've got a number from the 90s of classic Trek charactets: Kirk in the captain chair, Spock at his console. Also some of the older Star Wars ones that also light up with voices.
