Can someone tell me a little more about this sale? I don't see anything on VolksUSA.... (Also, they're discontinuing the ENTIRE 1/6 line?! I think buying up some freaking heads is in order *horrified*).
Okay, Volks and Obitsu,
embyquinn mentioned a lot of good points, but I'll add my two cents here. For me, basically Volks vs Obitsu is a matter of "sturdy" versus "style". Yeah, no doubt the Volks Neo Goh guy looks a hell of a lot better without clothes than the Obitsu bodies, making him especially good for those strapping young male characters that show chest/abs/etc. If your characters or customizing is going to lean in that direction, I'd grab a few. Female options are a little more even, it's just a choice of aesthetics because both offer around the same amount of articulation.
Volks is pretty "floppy", but many dolls can't stand without the aid of a doll stand, so if your customs are really leaning in the direction of a Volks, don't be afraid of them!
