Let me know what specific units you're after and I'll see what I have available. I can begin paint stripping within the next few days if you're still willing to wait?
OK, first things first..... Gaunts and lots of :D Terma/Horma any would be cool, but i know only Terma's can plop out from a Tervigon as i plan to make a 'Kraken Swarm' Army eventually....
Warrior's are another Nid form i like, shooty/choppy i don't mind too much
Stealer's, Meh...... haven't used them in a looong time back in 5th, so i don't know how effective they are nowadays, could be fun to see though.
Zoanthrope's look badass, and for their tank killiness as well...
Tyrant/Flyrant depends on what the loadout is, atm i can see myself leaning towards the footslogging version with scything talons/lash bonesword
Tervigon, for the troop producing capability and they look sick :D
Tyrant/Hive Guard for Tyrant protection/ and Impaler cannonness
These are the models i like the look of, and before you start stripping Serpion, wouldn't it be better to work out a price first and say what mini's you etc before we confirm a sale? incase we need to work out shipping if you live outside UK...
