I like eldar too
I have squads of first edition dire avengers, striking scorpions, howling banshees, dark reapers and fire dragons.
I also have some newer aspects as well, warp spiders, shining spears, 2nd and 3rd releases of dire avengers, the second release banshees and 2nd release reapers!
Im just waiting for a new book, maybe with some new aspect warriors [Slicing Orbs of Zandros anyone?]
Dire Avengers are my favourite looking aspect, with Horse hair plumed helmets. Sexiest helmets ever.
