Waaagh! vs. Necrons and 2nd Army

Played last night vs Necrons. Made a big boo-boo in armour pen vs the 'lith. Instead of rolling 2D6 and choosing the highest I accidentally rolled Str+2D6. oops. as such i popped his 'lith. And scored a sh!tloat of victory points.
current record with Orks: 4Wins, 5 Losses, 0 Ties, 44.44% Win.

On the plate for 1500 point Ork force:

• Model tank commander
  
• finish modelling drivers and gunners for buggies
  
• prime kan, tank

on deck for 1500 point Ork force:

• model burna boyz
  
• finish modelling nob
  
• make sure to have enough rokkit boyz (if not model more)
  
• buy Caddy model
  
• model/paint caddy
  
• buy other trukk model
• Make sure to have enough boyz

Picked up the Chaos codex. Really excited about starting the army. If I pick up a box it will delay the orks, but also if i get a box and assemble all the models it may put me in the mood to work on my orks more?

Want to have the orks finished for MOM, not sure if I will have time to do what I want to with the army. would like to have it all modelled and painted. would settle for all modelled.
