^I already own two of the RAH Medicom Snakes, but in my opinion, the Play Arts figure is on a league of its own. The entire look of that figure is so accurate, especially the head-sculpt. AND it's fully articulated. At only $50, you certainly can't go wrong. It sure beats having to shell out 200 bucks for an outdated RAH figure from Medicom.
Also, the Play Arts Kai figure has a limited production run. It was sold out in Japan in just a few weeks of its release, and it's being re-released in September for another limited run. You should get a pre-order in, if you're interested, before the price starts to increase.
