That is just mindblowing. That's what I'd love to do one day. It'd be an absolute blast. I can see it being relatively easy as long as u have the pieces. The time would be sheer fun.
And those look awesome, Fungal. Where's ur Aero Booster. I'm pretty sure u had one. I've only managed two Exo-Force figs (Iron Condor & Blade Titan) so far, both at $11 from Toy Kingdom. And as Jaydisc mentioned, I constructed one of them last night and they are amazing. I'm lookin' at some eBay auctions atm and hopefully will score a heap of them cheap. *fingers crossed*
