The single HT Stormtrooper is the only Stormtrooper I own, and I paid just a little above retail on the after market for it. In retrospect I just should have waited for the Han Solo Trooper, which should be the same height and be no different with helmet on. I now also have Luke's Trooper on preorder. I wasn't planning on getting more than just one Stormtrooper, but Luke was too hard to resist after seeing in hand pictures and so now Han becomes a must have too when he comes out. So, when it's all said and done I will have 2 tall Stormtroopers and 1 short Stormtrooper. More than enough. I think I'll pose them all primarily as Stormtroopers and only occasionally pose the other two as Han and Luke. With the long rifle I got in the Han and Chewie two pack I could pose each one with a different Trooper blaster (long rifle, regular blaster, and the pistol used in promo shots).
On a side note, this is my 501st post I have made since I joined the forum in 2009. I think the Stormtrooper thread is an appropriate place for my 501st post.
