I've been collecting vintage Kenner stuff and restoring them to back to new. Items I've done so far is the Imperial shuttle, two 2010 AT-AT's, an X-Wing, a Y-Wing, Darth Vader Star Destroyer playset, a Landspeeder, and an Imperial Troop transport. For me, it's fun to take a filthy dirty toy and take it apart, clean it, replace any missing parts and fix the electronics, and make it look like it just came out of the box. I find it focusing and relaxing. Retroblasting and Toy Polloi on Youtube are the bomb for restoration research.
Also, if it's all dirty and nasty, you can usually purchase them for cheap.
I'm also making a 1:18th scale bar/saloon for my Toy Theater project.
