I have used 505, 101, and june tailor with success, they all seem to be about the same for me. I use all outside because i don't like the smell of any of them, they all irritate me inhalant wise. The only one I have that I haven't tried is sullivans, but I am sure its comparable. 505 is the most expensive in the batch. I got all of them from joanns online. I think mettler just came out with one as well
