Here is the list I'm going with at the moment (with some changes that were previously recommended). The reason for some of my choices were based on what I could afford to buy and what was included in the DE battleforce boxes which I used to build the core of my army. Now I'm thinking of adding scourges to the mix. This is mainly because they are amongst my favorite miniatures in the DE line. I'm debating how useful they would be though and if I would be better off beefing up my troops if I'm going to 2000 points. I usually ran my BA army with a lot of jump troops which worked excellent.

What I was thinking of was adding 2 units of 5 Scourges with eilther dark lances or splinter cannons depnending on if I decide to go anti-infantry or anti-vehicle. I don't like the short range for the other weapon upgrades. A lot of times I would have to put them in vulnerable spots to get off a few shots and I think such a small unit would suffer.
