Michi, already have a hazardous good sheet on order for pickup at Crisis...sadly, you only get 2 of each sign, no where near enough for my (weird) needs.
Fastolfrus, I really prefer decals over sticking paper to signs, just more practical for me I guess.
Modhail, Kruidvat, though I think Pippoos has a nice selection too, the models vary a lot though.
