The Arms Microns are great. Take a look at the AMW line, they're the Micron kits that are sold individually, so no need to shell out twice the price of a US figure just for the weapon, especially when the AMW are about a fiver.
I've picked up 5 of the first 6 so far, and they're great. Could do with better stickers maybe, but if you're into model making, then you probably have some paint that'd be better to use anyway. I'm actually waiting on 04-06 being delivered, so I'll have 2 of the gun and the chainsaw-cat. There's also a couple of gift-sets up for pre-order with I think 5 or 6 of the Micron kits that have come with the main figures. One thing to note is that each release of the Microns is in a different colour, so if there's a particular deco you're after, probably best to bite the bullet and get it, if it's one that comes with a bulk, just sell that on later or customise it.
Lastly, Arms Micron Capsule toys - these aren't quite as nice as the proper Arms Microns, but you don't have to build them.
