Mind you, we are just looking to replicate the jackets, helmets, and blasters. Of course, I can point out those who are interested to places where you can get bodies, heads, suits and boots from.
I can also steer you away from the ones that have crap bodies and heads.
For bodies, go to these places:
www.drmego.com; and castaway toys.com.
If you want vinyl male heads, go to classictvtoys.com, and get a few of the loose male heads.
One person I know used a Jefferson D'Arcy for Starbuck, and a Tony Vedeschi for Apollo. Believe it or not, they DO work.
For female heads and excellent bodies, DocMego is your man. However, the female head only comes in Caucasian, so if you want her to become African-American or whatever, a dye job, face repaint and hair reroot is in order.
To skip all that, get the new Lt. Uhura doll that EMCE came out with. or even some vintage ones that you can get on Ebay.
I even managed to score the African-American Dinah-mite figure, but she's pretty rare.
Doc's bodysuits are all made in China, as are the boots, etc. Get the tall Klingon boots, and cut the top off so that they are even all the way around.
Doc also sells the EMCE new Star Trek figures on his site. Just click the appropriate link.
