Differences in Medicom Vader #1 & 2?

[Mookeylama]

what are the differences other than head sculpt.

and do u think the price will come down or should i just get one now?

I say get one now! The ROTS one is really nice!

[Mookeylama]

i'm really close to getting him. and 2 stormtroopers! BTW, what are the best Stormtroopers out now? Medicom's newest looks good but so do the older Marmits.

oh, and back to my 1st question. what's different between 1 and 2? i heard 2's wrists are more articulated or something?
