Wor-Gar's pic shows how well sculpted and accurate the Stormie is (except for the dang crotch) but Lee said it best, the armor "feels" cheap. It lacks the sturdiness of the Medi armor even though it's rigid and that slight gloss that the Stormies have as well.
If the armor is like CW Obi-Wan then I don't see how you can say at all it feels cheap. If anything the Medi Armor feels like cheap rubber. If these guys are supposed to be wearing armor its most likely going to be a harder material don't you think? There is nothing sturdy about the armor on the Medi as it seems more like a bendy material. Where as the armor on CW Obi-Wan is sturdy and won't bend as we know it will break.
I know if the armor is more like Medicoms and less like CW Obi-Wan I'll be quite disappointed when mine gets here.
