With this unit, I bought the Phobos Strike Team KT box rather than the Infiltrators/Incursors dual kit. I very much recommend the former. Its bits give the otherwise bland models a proper SM feeling, particularly as seen with the Druht leader. I've never really been a big fan of Phobos since I reached hobby 'maturity'. I don't mind how they executed the tacticool look, but the basic troops are lacking on ornamentation without the upgrade sprue. 
 

With the Haywire Mine guy, I brought out some Hexwraith Flame and put a coat of that over a metallic basecoat to sell the archaeotech nature of such a device.
