I actually picked up the coat from
www.echobasetoys.com for $16 - it's a Sideshow Collectibles Buffy the Vampire Slayer "Vampire Spike" coat that was included with this figure here -

You should be able to find one at
www.echobasetoys.com as they just parted out a few of the Buffy figures - good luck!
As for Raiden's suit - YES, the vinyl suit is a multi-part suit which is the major problem with it - had Medicom designed it like Hot Toys designs their rubber/vinyl body suits (which is a solid one piece over the 1:6 scale body), there may not have been as many problems w/ the seems tearing - there are - as far as I can count - at least five seams on the figure - both shoulders, both hips, and a small one right in the crotch. The hip and shoulder seams are the worst as they not only have the likelihood of tearing if stretched, but they also warp or tear the paint loose as well - Raiden's ass on mine is all funky on one side from where the seam pealed some paint up
Otherwise, it's a great piece to LOOK at, but nothing you'll want to touch too often - even the knife and sword sheath are a ^^^^^ to get on (and keep on)
