I wanted to post an update in here as I just got my order of Warp Stalkers in today.
I say, if you like the concept of these guys, ignore the haters and order yourself some. They're very nicely cast. I took a couple of photos of one of the figures just so people can see some of the details.
The casting quality is very good. There's flash, yes, but that is easily cleaned up. I saw no air bubbles or miscast pieces here. My previous order from them for some Rhino bits had some, but these were totally clean. Details are sharp and crisp and for something hand sculpted, they're really impressive. The one and only flaw in my entire set, other than a couple of warped weapons (which can be fixed with hot water) is that one guy had a noticeable mold line. That's it. That's easily cleaned up, too.
I know a bunch of you guys were saying how the figures looked really thick and chunky and generally too big. I took a so-so picture of one of the guys with one of my Fire Dragons so you can see that they're really about the same size and thickness are regular
GW Eldar.
It was a little hard to pose them together decently due to the one guy still being on his sprue, but I have them posed at about the same height. As you can see, they're pretty much the same.
