I've got all the Kotobukiya figures from the OT on order, except the first Vader who I've bought from a boardmember and should come in in the next few days. A local shop was having a special offer on them and I thought I might as well complete the set in one go. Ought to be a couple of months before they're all in though.
Anyway, while some collectors frown at the material and the look ('big action figures' and what not), I think that suits Star Wars. And if it keeps the price down, so much the better.
Could someone perhaps be so kind and take a picture of a Koto figure next to a SSW statue? Josh said they're practically the same size, but I think seeing them together would make envisaging things a lot easier.
