Yeeeep, seconded. Excellent stuff. I'm rebasing all of my scatter terrain at the moment (ugh) and it's 90% ainsty. I think Pegasus Hobbies do some barrel sets but you'd want to tone them down a bit.
Pegasus Hobbies also does some excellent fences - they start off a bit crap, but can be saved into some really decent stuff. Most MDF laser-cut companies do crates and wagons (I have a bunch of 4Ground wagons and carts - and outhouses, and sheds...)
