>>10061312>>10061400Like the others have said, plain Stormies are a little hard to get a hold of currently. Most of us would recommend the Black Series (Mando version) for army building. There are several different variations of that mold now, some easier to get than others. For some silly reason Hasbro made the basic version pretty scarce and it goes for unattainable prices unless right now. So, unless you are willing to pay astronomical prices, you might as well settle for a variation or an important figure. There is also the S.H. Figuarts A New Hope and Rogue One Stormtrooper. These are extremely accurate to their said films but cost a fair amount of money on the secondary market.
On a side note, I really think we should make a buying guide for Stormtroopers and Vader. We get these questions a lot in this general and it would be really helpful for people trying to get into the scale
