Shimano 105 mini group with 600 rear derailleur $60
Campy Triomphe mini group $75
Suntour Sprint mini group $75
All groups contain all parts and function perfectly to my knowledge. Parts are a little grimy and scuffed but should clean up for a decent rider. Campy is friction and the other two are index I think.
Let me know if you need more pics of anything. Will ship to lower 48
