Okay, so this year I plan on entering the Armies on Parade competition, and I have found myself conflicted between these two armies: Thousand Sons (or another CSM legion) or Salamanders.
Now, I also plan on playing these forces at some point, and I have a $200 budget on all models for the competition. Any help/advice would be welcome!
A few things:
-I have a primed megaforce of regular marines, but I was planning on using that on another chapter
-New CSM codex soon, it may be worth waiting for the models from there
-I hate painting metal, so any A thousand Sons marines would likely be converted in some way
-I'd also need a board idea for each army, I'm thinking prospero-like world for A Thousand Sons, and desert army outpost for Salamanders

Thank you all in advance!
