What should I do from here?

Hello folks

So this is going to be a bit of a long winded post but I need some input from people who know what they are talking about. I am a long time ork player and am just getting into dark eldar this edition because I have always liked the models and wanted to mix it up a bit from the greenies.

I managed to pick up a whole army lot that goes a little something like

3 raiders
1 ravager
1 razor wing
1 voidraven
2 venom
2 archon
Succubus
Lilieth
1 haemonculeus
20 kabs
9 reavers
10 blaster born
1 talos

Harlequins
15 players
2 shadowseer
2 deat jesters
2  skyweavers
2 troupe master
1 solitaire

And the full triumverate

My question is where should I go from here? I got a pretty good deal on the lot and the last couple $ I had set aside for this project I would like to round out the list. I don't have much money left over probably 50$ or so but will set aside some more in a month or two. Should I get a star weaver for a troupe, or maybe some scourges? I really don't know. I am attempting to play some much different from orks general game play and I would describe myself as a semi competitive player in a semi competitive to competitive environment (no cheese and we have a tournament or two every couple of months). I feel what I have at the moment is lacking in overall darklance firepower and cc cohesion but again I havent played with them yet just been trying to get everything assembled and painted and reading as many threads as I can.

Thanks in advance

For your first purchase after this, I'd recommend a box or two of Kabalites. Looking at this, you have 50 spots avaliable on transports and only 30-35 people to fill them. A box of Kabs (even Wyches too, probably), will help you garner CPs more easily, and give you a nice core force to expand on. Scourges are an excellent choice for AT, and synergize very well with Ynnarri, but as you have a two fliers and a Ravager, AT isn't an immediate concern for you. I don't play Harlequins, but a Starweaver or two would certainly be a worthwhile choice. If you're not opposed to taking in Eldar allies, a Farseer Skyrunner will give you a mobile HQ with Doom, something that will add a very useful force multiplier to your offensive output. All of these options should be avaliable for under $50. For longer term purchases, I'd recommend another Ravager or two, Scourges, and some Beasts, particularly Clawed Fiends, Khymera, and of course a Beastmaster. The GW models for the Beasts are, honestly, unimpressive molds cast in unimpressive finecast, with an even more unimpressive price tag. It's easy to convert a Hellion to the Beastmaster, and there's plenty of guides here, and other places on the Internet, on kit bashing some unique and terrifying monstrosities for your force.

Overall, I think you have a very decent core force here! The playstyles between Orks and DE are different in a lot of ways (we usually play something akin to a mechanized Kult of Speed), so if you haven't done so already, hopping into the tactics and listbuilding sections will help make the most of the models you have.

Thanks for the great response! My plan is to have a 1850 pts list ready for November for a tournament a local shop is holding.
