Bought my army yesterday; did I get a good deal?

First time DE player. Picked up my army off Kijiji, not entirely composed of models I want but pretty close so I figured I'd go for it.
-Archon
-Lelith Hesperax
-Haemonculus x2
-5x Wrack
-20x Wych
-20x Kabalite Warrior
-10x Hellion
-9x Reaver Jetbike
-3x Raider
-1x Ravager
-1x Venom
-10x Incubi
-10x Mandrake
-Codex, 40K Rulebook, and army carry case.
I paid 400$

My questions are twofold; I'm pretty sure I got a decent deal, but was it worth it for the model selection? Can I use the models I've got to make a decently competitive army?
Thanks for your time, ladies and gents!

Deal seems pretty good to me.

I think what would be nice is a venom or two more.

Other than that it would come down to playstyle and what more you'd like to field.

You got the essentials for a DE army, you got a more than execellent deal

3 raiders plus 20 warriors alone is enough to say thats good plus 9 jetbikes plus 10 incubi lol
You got an awesome deal hope you keep playing Dark Eldar cheers

Sounds like you got a great deal. Build a list you like and post it, then we can show you some other ways to use it.

Cheers folks.
