I have been wanting a couple of wool jerseys as well but the price puts me off. I have been known to wear an old wool sweater on a cold ride, and it works well, it just doesn't look too great. The woolistics look great but they do want an arm and a leg for one. The rivendells look nice, but not as stylish and are a little more reasonable.
