I just received my Hitachi Magic Wand (with the attachments) today. All I can say is WOW. The g-spot attachment had me gushing in no time. What a joy. I could never find a vibrator with the power I needed; but that is in the past. Now I just have to make sure I fold up at least one bath towel under me for a quickie and have several on hand for a longer session.
The power cord is on the short side and the Wand has only two settings, so I recommend getting the Magic Wand Controller to extend the cord and give you more control over the speed.
