I've got a handful of them in that last few weeks and I'm pretty satisfied. Just as detailed but far lighter than their pewter counterparts, the finecast minis are also easier to work with.
One did come with a void in it, but it wasn't that hard to fill with gap-filler putty.
A price drop would have been nice, but when does the price of anything GW ever drop? It's only a matter of time before pewter is phased out in favor of resin or plastic, so better get used to the idea.
