After the earlier discussion, I went looking for pictures of them that weren't the GW studio minis. I found a bunch on CMON that I actually really liked, and decided that the problem wasn't the models, it was the way GW had painted them. I looked around at some painting tutorials people had done. Then I went and read through all of the fluff sections in the new codex, to see what their deal was and why they were around. Then I decided that a unit of them might be fun to paint, and would give me some variety. I've still got Rubrics, but now I also have Tzaangors. Currently I'm trying to figure out what colour I should paint their tabards in order to fit them in with my army fluff.
Also, I've never liked doing complete proxies, probably because of the old WYSIWYG thing. Which means that if I want to try some out and see how they work, I need to buy them.
