My Group just plays with the basics (Core, Advanced, Bestiary I+II, Ultimate Combat and Magic) but is getting more and more off the mainroad - we getting interrested in 3PP stuff and looking for good (and especially useful!) stuff.
The only of your products I know is the '30 not so mundane items', but after reading it I know we need more of these rules.
Good quality and many ideas our group will never have on its own.
