One of the armies I played against at GD had one of these fellas in it and I got to look at it. It really is a nice sculpt but no more so than any other metal UH. I have some personal distaste of the weapon (which doesn't match any other UH weapon) and thought maybe just a Berserker sword would be more appropriate as a 2H weapon for him, but I know that is kinda picky on my part. And it did die just as easy in combat...
I do understand the collector-mentality and have a few "prizes" that are rarely appreciated. It's always cool having a rare model to play with. It's just hard to swallow the price of an entire boxed army for one Hero...and an unnamed 60pt generic Captain at that.
