If you're looking for a nice vibe, this is my current object of lust:

I also love my glass "bloop wand":

IMHO, stay away from the penis-shaped vibes...they're too stiff and hard to use internally (sounds counterintuitive, I know), and they're not particularly versatile as vibrators. Go with a smaller vibrator, or a silicone dildo with an attached external vibrator. Also, read up on the Blowfish site's FAQ about different materials and keeping them clean.
