I was just investigaing carry cases (my 1500pt Ork army is soon going to include a Warboss, three Kans and a Dreadnought!) and having checked on Oracle Games for non-GW ones, I thought I'd compare them to GW ones. While there I noticed a Citadel Masters PAintbrush set!
Now I know the quality of your tools makes a difference, but £75 still seems crazy I need a new Standard brush, but I'm going to see what the local planes, trains and automobiles model shop can do instead of paying £2 from GW
