There are lots of different options out there but ultimately when it comes to handles it depends what you are looking for. I'm not a huge fan of rocket vibrators although I know there are a lot of women who swear by them. I can feel vibrations in the handle of mine and will often uses the side of it instead of the nodules end as a vibrator.
How experienced are you with toys? Are you looking for your first or is this for part of a collection?
