That Tsukihime figure set is over 4-6 years old. it was also produced in limited run. the only way you are going to get it is by going to toranoano in japan or finding a replica set from china or possibly someone may sell it on an auction site. I was actually going to buy it when it first came out but I changed my mind for some reason.
it was made by Spring

The FA4 Figure Collection came out last year, you can easily get it off ebay or another auction site most likely.
but be prepared to spend 60-90$ for it, as the box originally sells for over 50$ and now you have to pay a premium.
try contacting this guy on ebay if no auctions show up (I think there are some though)

That last ciel you posted is a resin kit. that means you have to build it yourself. and it was also produced in a tiny run, so you can only find fake replica kits now but that probably doesnt matter much to you if you plan to have someone else build it.
I dont know about that website u posted. you could contact them and see how much they charge to build it.
this Ciel is still available

EDIT:
OK I got my charu in
the packaging is good again and the box is quite big
the figure is not attached to the base, in fact, the wall piece itself is seperate and can be removed from the base
the figure loosely sits on top
I really hate when they do this, why? does it really save that much money in production costs?
