A few months back I bought one of this the figure featuring him in the first Mega Man X's full armor [http://www.gunjap.net/site/wp-content/uploads/2011/04/3121.jpg] is readily available, I prefer him without it, and you can't take it off, although the original's parts are interchangable with the armored one's.
It was one of the few purchases of whimsy that nagged me for quite some time, and he generally goes for a hundred dollars or more, so when I saw him for eighty on Ebay, I had to go for it. I regretted the purchase for awhile, because that kind of price is rough for someone as frugal as I to swallow, but fuck it, he's awesome, and there are tons of ways to pose him, so the remorse eventually faded.
I plan to grab one or both of the Zero figures as well, just because X occasionally looks lonely there on my computer tower. Plus, I can steal his saber and give it to X to replicate X6, but now I'm being a nerd, so I'll stop before someone gets hurt.
