When you decide to make the plunge into some camo, I recommend picking a pattern that you like then going hog-wild and buying new.
Surplus is a real crap-shoot and depending on the competition where you live can be way over priced.
Surplus OD Canadian BDUs:
Anywhere from $15 to $40 per pants/ tunic
Surplus German Flektarn BDUs:
Anywhere from $30-$50 per pants/ tunic
Brand-New Brand-Name US Woodland:
$42 + shipping per pants/ tunic at Stapleton's
You might say "$100 bucks for pants and a shirt to wear?! That's crazy.", but if I could have all the money I've spent on mediocre recycled clothing back, I could buy a new AEG.
