Don't take this the wrong want or that I am being an butt. May you please narrow down what you want for an 1500 or 1850 list since only $250 your pickings might be pretty narrow or someone can sell you a load of

and tell you that it is competitive.
Questions about what you want:
what armies do you not want?
new or used models?
do you care is the models are 2nd, 3rd or current edition figures?
fully painted, primed or bare plastic or metal?
Please post these answers on your thread because most people will look at that and go, whatever. The list is only quarter of what makes up a competitive army, it is the person playing the army that makes or breaks a list.
