I've got mixed feelings about the alternators. I have a shelf full of them, along with anniversary Optimus. Classics Bumblebee and Cliffjumper are up there, too, because they look pretty good, scale-wise.
I worked hard to build up that collection, and I drove my wife crazy while I tried to track them down. But when I get sentimental and start to transform them . . . those sentimental feelings disappear pretty fast.
I used to have Smokescreen, Silverstreak, Prowl, Binaltech Blue Tracks, Binaltech Yellow Tracks, Shockblast, Hound, Grimlock, Sideswipe, Sunstreaker, Mirage, and Skids. Then in 2007 I had to transform them all back to car mode so I could pack them up to move, and that was such a miserable chore that I eventually sold everything but the blue Tracks.
I do sometimes kind of wish I'd kept Shockblast, just because it was such a fun reimagining of Shockwave. But, I have the little NewAge Legends Porsche "Cyclops" to scratch that itch. It takes up much less space and is much easier to convert. I just wish it were in G1 toy colors.
