The Spider Droid isn't terrible, but of course seeing that big, nasty, white, wind up dial protruding to activate the walking action feature is NOT cool. It also looks pretty small, scale wise. But like I said, it's not the worst thing I've ever seen - not half bad.
The Trade Federation Tank was a pretty nice vehicle it's first time around in the Episode 1 line, but I know that it was very hard to find for many people, so for that very reason I'm all for seeing it re-released. Besides that fact, it's an "army builder" vehicle, so I'm sure some people would like the chance to pick up a few extras as well. Bring it on!
