We've got a hitachi magic wand, and it's worth every penny. Not only does it work well as a nonsexual massager, it gave me my first "hands free" solo orgasm with no movement, and my wife can orgasm in about 60 seconds flat from it.
other favorites include:
The Scorpion, a triple stimulator, from
www.safesexmall.com
Bondage Tape, cheapest place we've found it at is
www.subshop.com
a cyber-skin butterfly (basicaly a strap on bullet)
and our newest item, the liberator....it's basicaly a very firm foam pillow. we've got a wedge, the smallest one, and it's great. not sure of the site, but google it and it'll pop up.
