Conversion pieces

Been looking around at some of the bits that companies like Chapterhouse sell, and I like their Spartan helm design, but hoping to find Spartan helms without a plumb. Anyone know where I can find those and maybe some wings that could match these guys?Attachment 15570

Update: Ok I stumbled onto Hitech Miniatures Spartan Helms, which look awesome...Attachment 15571now to find some feather/mechanical wings like the ones on this guy without having to recast the ones I have for the Prosecutors.
