I've just received my first finecast model (Isabella Von Carstein) and I'm actually pretty pleased. Maelstrom may have taken over a month to get it to me, but they picked out a smegging good one. There are no large bubbles, just a couple of small ones on the underside. There are some mold lines and flash but I will tolerate that, and there's a little nub on the chin I will have to remove but no big deal. +1 for finecast for this model.
I remain pessimistic about the whole failcash endeavour, though. Shortly before receiving my model, I had the displeasure of working on a friend's (I was just undercoating it for him). It was a wood elf noble with great weapon and it sucked. The cloak was bumpy and uneven where it should have been smooth. There were large and small bubbles scattered all over (including one that removed the tip of the cloak, and one that occurred dead centre on the top of his head) and some miscasting on the weapon. -1 failcash.
I will post pictures of these when I get them from the camera. In the meantime, while the quality of finecast can be reasonable I still prefer metal. Actually I'd like to see GW release metal versions of finecast models as limited editions. I'd have snapped up Isabella when she came out, ordered the Empire witch hunter, helped myself to a handful of necron characters and a tomb king liche priest if they'd released some metal ones in limited numbers. I'd even tolerate another price hike to get this. As it is, failcrap has put me off buying any of these models. Even Isabella was a gift. I wouldn't have bought her for myself.
