Sllayer is good stuff and they have a forum to the website that's very friendly and people's customs there are amazing- lots of direct communication too.

with casting, it's all timing things right- these companies generally cast up big batches of parts overy couple of months or so on a basis of only what's been preordered.
that means if you order just after they had their casting run, it'll take a couple of month's before they make your order.

Casting is a pain for small stuff and Slayer's quality control is really good- meaning the casts dont have air bubbles or pinholes that need filling- which also means they have a lot of waste, so casting to order is just good business sense.
