The fixed stock is friggin nice... much nicer than I initially pictured it would be. Still, if you can use some imagination to picture how badass the folder would look in that last pic, I think it's worth the extra wait.
For collectors purposes, the fixed stock version is much rarer than the folder (even when it comes to the original Type 81). At some point it will be a unicorn in the collectors' market, kind of like them Valmets are today. I would think TI would probably order folders exclusively on the next one, since they've sold out the quickest. This would make the fixed stock ones pretty scarce.
Hmm... decisions, decisions.
