perhaps it should be noted, asterisked, or footnoted on the wiki for soap that are not good for sensitive skin. Perhaps even add a sensitive skin friendly budget soap to the list.
I have super sensitive skin so even if I was going for budget items I would want to make sure I didn't use anything that is harsh for my skin and would be willing to up my budget for soap that suits my skin better.
However if I did not have sensitive skin I would probably say, hey I can go get that stuff at walmart right now for $10 and try it out, and if it's crap I can always replace the soap but then I have a starter brush and bowl.
