I'd agree that Base states is the way to go if you're only only going to have one Fourze.

I also have module sets one, two and three, and I'd reccomend at least getting one, since it comes with Launcher and Radar to round out the switces on Base state's belt. It also has Magic Hand (which is good for some fun poses, especially if you have TaToBa and a stand or two) and Camera (which is ... good for what it is. It's a TV camera mounted on his arm).

I's personally also give three a thumbs up, since it comes with five modules that all look pretty cool.
