There was a real effort to get known authors to write Trek scrips in the original series: Robert Bloch, Norman Spinrad, Theodore Sturgeon and even the notoriously difficult Harlan Ellison.

Did they try to do this for any of the later series?

Maybe they did and I just don't know about it?

I'm considering adding a Galvatron figure to my collection.

Which ones are considered the best?

Which ones should be avoided?
