I used to be an acrylic and cotton gal until I used Madelinetosh's line of yarn, especially the Vintage. It's so soft and springy. No itch at all. You wouldn't even know it's wool. This yarn has converted me from a cotton to a wool gal. The colors are awesome and the yarn is so nice to knit with. My new favorite yarn.
I love Madelinetosh yarns. The colors are wonderful and it knits up like a dream. The hand-dyed nature of the yarn means that you may have variation from skein to skein, but usually this isn't a big problem.
