Which soaps are causing you to itch? U.S. made soaps or European soaps (or both)?
European soaps tend to have much higher standards for allergen testing... there are several nice hard milled French brands that go for $20 or less.
That said, I'm a huge fan of Tabac, but some of the French brands have a nice scent if you want to try something different. Theophile Berthon in particular comes to mind.
