Old Faithful
I found this in 2002, and have been using it ever since (I've had it replaced a few times).  It's a sure thing, less than 5 minutes, and can even be hands free if you want!  The newer one (it's lavender with a wierd cup thing on the clitoral stimulator) is horrible - the silicone isn't as soft and I think the stimulator and the shaft are too close together.  But this one is absolute perfection.
