Picked up some more models. Looks like I'm going with the Combined Army faction, at least to start with. Not bothering with Sectorials at this stage.
Current list of owned models:
Raicho (HMG+Heavy Flamer, no pilot yet)
Charonid (Plasma Carbine)
Malignos (Combi-Rifle)
Med-Tech Obsidon Mechanoid
Slave Drone (2)
Reasoning of purchases:
Charonid (new version) is an excelent looking model. He's also got a Lietenant + Hacker option, which seems good for a starter player. Also has the G: Mnemonica, which makes my lietenant much more survivable,
