Hope OP is still around.
A few weeks ago I ordered a small box of stuff from Coolcastornot, to determine quality over a few products and see if they'd be a regular to buy from. I picked up a random resin model, a forgeworld model (so I'd have two different companies/moulds/whatever to compare) and some brass etch.
The brass etch is a touch thinner than what I've had from Forgeworld and Secret Weapon mini's, and is thus easier to work with but also more likely to bend on accident. Detail is sharp and crisp and honestly can't tell the difference at a glance between any of the companies.
For the resin, the resin itself is visibly different to what GW and FW are using. It's closer to FW, a more solid and brittle version to what finecast is using. As for the quality, that's really going to be up to you to decide. I rate this higher than every Finecast miniature I've dealth with (half a dozen to date) and on par with my FW experiences (hell, there's no warping on the whole vehicle kit whilst my deathkorps needed every gun soaked and straightened).
You will notice in the image given that the lines are sharp and crisp, my iphone sucks for macro photography, there is a single bubble on the pilot's wrist that I can fill with glue. These haven't been cleaned, straight out of the baggie with a dry-fit.
Postage took roughly 2 weeks, I'm in Australia and I payed for postage instead of leaving things to fate.
