I looked at some other sideshow SW collectibles and they're just as expensive as medicoms.
Please read-
Usually sideshow collectables are like 60-150 bucks
Each figure varies in price though on how rare they are.
A few Sideshows are just as expensive as Medicoms, and a few Medicoms are just as cheap as Sideshows. However Medicom is almost always more expensive because they have more detail and more accessories.
You can see the big variation in prices-
