There are lots of good handsoaps. I've been using Trader Joe's lavender handsoap. Ideally I'd use a fragrance-free one, but I really like lavender.
Just be sure to avoid any soap that contains harsh sodium lauryl sulfate (SLS - not to be confused with the gentler sodium laureth sulfate, SLES, although some folks don't like it either), menthol, peppermint, or anything that makes your skin "tingle". Look for little or no fragrance too, since even natural fragrances can subtly irritate skin.
