Depends on the 2pack really. Some can go for about $100 or so and others could be up to $300+. As mentioned items that show up on Buyee are usually a lot cheaper than what many sellers want on eBay.
On these early Max Factory models I guess they did several versions. I have a gray one I put together and then resprayed with gray primer. And I have a second one that has blueish purple vinyl instead of gray and it stands almost an inch/ 2.5cm taller than the gray one. Both appear to be original Max Factory kits boxes and all.
If you decide to buy all the volumes the best place I have seen to get them is from the Japanese site Buyee. You can usually find all 32 cubes for under $100 + shipping.
Really like that they did Aptom Omega Blast and Guyver 0. Nice to have some new characters. I think they all look really good. Aptom will definitely be on my list.
Dr Balcus is actually a copy I got from UnitG. Got it along with Aptom in a processing tank from him. Love them cuz they are actually way better looking than the originals.
I would think if a host took a bullet to the head or some other forms of immediate kill the unit would be lost as the host would not have had time to activate it.
Looks like my shipment hit the main dispatch Center in Houston TX this morning. Should leave and be at my post office hopefully tomorrow. Tuesday at the latest.
