Thanks for the kind words everybody (I forgot to say that in my first repy...)
I've thought about casting my own, but the 2 piece mold is too hard for me to understand and execute. (I'm just a cave man)
I got some Cast Heads from Good to Go or Aly's Corner, but I would still have to dremel them out (even more because they are solid resin casts) and then Paint them. So they ended up on GI Joes. They are about $3 a piece (and worth that for sure), but by the time I have to drimmel and paint them (which I am not really that great at) it is easier just to get a cheap figure at a convention or ebay and dremel the head out.
I have a few other customs I have been working on (mostly in the kitbash/head swap area) that I will post as well. Lets just say this was a starting point. Baby steppin....
My goal is to be able to add knees to Imperial Officers, Elbows to POTF2 Endor Rebels and both to Saga Hoth Luke and of coure non Jango Heads to every removable helmet Imp that is made from here till the end of the line.
