500pts DE List made with 2 start collecting box sets

Just starting Dark Eldar for the first time.

Heres the preliminary list I have come up with:

HQ:

Archon (could be converted into a Homunculus using Admech bitz and bobs I have lying around)
w/ Shadowield
100pts

Troops:

10x Kabalite Warriors
w/ Raider (Disintigrator Cannon, Night Shields, Splinter Racks), Splinter Cannon
180pts

5x Kabalite Warriors
w/ Raider (Disintigrator Cannon, Night Shields), Blaster
145pts

5x Kabalite Warriors (objective holder)
40pts

Fast Attack:

3x Reavers
w/ Heat Lance
58pts

Thoughts? I have little experience with Dark Eldar, so any C&C would be much appreciated.

Why don't you try Purge Coterie formation? It fits in 500.

Hmmm I could, problem is this event we are running you can't change what units are; so if I make the Kabalites Trueborn, they have to be Trueborn for the rest of the event (I was going to have some blasterborn down the line but not this early).

So it could be a problem, alternatively I could go with no one in the raider and 20 kabalite squad I guess.
