[Kamen Rider Die]

Okay, SHODO.

All these excellent pictures of Riders of dubious effectiveness have got me interested in maybe adding these tiny mans to my other collections of tiny mans. But, in trying to get an idea of which older figures I might want to grab, I see that there are three series of SHODO: VS, X, and O. Am I getting that right? How do they work together in one collection? Am I going to look at, say, Kiva (from VS) next to Kaixa (from O) and think they look awful? Or are they pretty good together? I got an OOO and a Birth already (from VS, I think?), are those still pretty representative of the SHODO output?

I'm really thinking about trying to nab some of these figures, but I'm curious what SHODO collectors think. Is it worth going back to VS? Anyone got a good site to find older boxes? (I zero percent want to buy cases with Showa stuff I got no use for.)

Thanks in advance, and I don't know why I even come to this thread when I still have to buy food and pay bills.
