2 done, 3 more to go!

Here´s the Dark reapers that i bought earlier this week.
I think these guys are fairly underestimated. Well, they´re not cheap stuff so do onlu use them if you know that you can spare enough points.
I have played a few games with them already, and found that they NEVER lost more than 1 member and ALWAYS killed atleast 1 enemy squad.
The reaper launchers are one of the best Anti-marine weapons that i know, 2 S5 ap3 shots is DEATH to Space marines. I think that my blog-keeper knows that too (Moahaha).
Another good but pricey option is their Exarch that can field the totally apocalyptic tempest launcher, 2 S4 ap3 BLAST shots. oh my good...
For a few points less he can also bring an eldar missile launcher, but i dont think that it work as good as the tempest due to its low rate of fire.

As all other Exarch he can also buy some interesting abilities, but none of these do actually help the squad he is in, fast shot increases HIS rate of fire and crack shot allows HIM to re-roll to wound and HIM to ignore cover saves. (selfish guy, isn´t he?)
Well, as i mentioned above, 2 Dark reapers done, 3 to go.
The paintjob isn´t very special. chaos black undercoat with a fortress grey highlight followed by skull white, helmet is bestial brown basecoat and then worked up to bleached brown.
The gun was basecoated in scabred followed by a highlight of 3/1 scab red and skull white.
What do you think of them?
