SCS's Oakmoss and Lavendula is nice. Her Lavender EDT is a decent one-note frag as well. My favorite though is Floris Lavender. It is not your grandmother's lavender. It is a bit more spice than floral and lasts all day.
Never tried the Lavender SC from Sue so I can't help you there. Floris' Lavender is actually offered as a ladies edt but it works for both sexes. If the Floris site doesn't still offer it I will be bummed but it should still be able to be found on the 1 million or so perfume sites on the interweb.
