I found more stuff as I've been cleaning up, I figure this stuff might be good for really small robots. I found some tiny motors and gears all of which mesh with each other, so lots of gearing options. I think they run on up to a 1 cell lipo. $15 shipped
I also found some bigger brushed motors still on the small side ranging from 6v-18v. They are dirty from sitting in a box of stuff with some batteries for years, but they all seem in good enough condition to work and clean up well. More will be included if you buy all as I find more laying around. $15 shipped
And pictured are also 28mm brushless motors 900-1200kv, uses 2-4s lipo
