With carpal tunnel I can understand the hesitation with the Hitachi, while the most powerful of them all and very thrilling with the attachments, the weight of it is a concern for long term use. The Hitachi also only has two speeds, Hi and Low, the others following have a variety of intensities as will as vibration patterns. I would suggest the Large Lelo, I've got the black one or the Mystic Rechargeable Wand. I have the battery operated Mystic Wand, it was my first wand ever. Today if I had the choice I would get the rechargeable but since I have the Hitachi (54.99), Large ($169) & Med ($129) Lelo's plus the battery operated Mystic ($69) one, I think that's enough for me for now.
I don't know enough of the Fairy Wand but if you're looking for a wand without worrying about recharging or batteries, it might be your best bet. The Mystic Rechargeable is 74.99 right now but is out of stock. 9link
