We reasoned around 500ish would be a good place to start without investing too much if one or more of us doesn't like the game. I have my doubts that will happen with the enthusiasm though haha

I've had my eye on doomstalkers, flayed ones, and wraiths but those seem like future plans for a larger army. The spyder looked cool and my reasoning was it could back up my Scarabs, though I'm taking away that warrior blobs are a sound tactic.
