Hello Karen! Welcome to ATP! I only have three that has fragrance, Zygopetalum, Oncidium 'Sharry Baby', Maxillaria tenuifolia. But there are more out there. Usually I get to see them during orchid shows, or from other online orchid vendors, or if you go to the orchid nurseries directly.
Search for the websites of andysorchids, or seattleorchid, santa barbara orchid estate or try browsing around ebay.
