They indeed look very nice, and they're very cheap! I like the medieval-ish look, instead of the viking-like look of a lot of fantasy dwarves. Since I'm thinking of converting one to Tyrion, that's a big advantage.
Anyway, I ordered the dwarf I was looking at, and will compare it to one of my own 28mm humans when it arrives. Judging by those pictures, it shouldn't look too bad. If the head of the human looks good enough, I'm going to buy one of those crooked dice head packs. If not, I guess I'll have to find a better alternative...
