The problem w/ rabbits are that they just generally aren't built all that durably. A good number seem to tear themselves apart during use, or sound like they're going to. Which, just isn't sexy. Even as a guy I find it a distraction.
So, you end up spending $100+ (Unless you shop online...) for one that's fairly quiet, but the controls basically suck and are difficult to operate when you're not actually looking at them. Well, except for the rabbit Pearl or the other number of knock-offs that have the controls on a cord, and take C batteries. But then you go back to cheap ones that tear themselves apart.
Of course, it really depends upon what you're using it for. Most of the ones in the above photo look to be strap-on harness compatible. Which you can get w/ vibrating micro-eggs that go into the base.
Then the question is g-spot or no, or ribbed, or waterproof or... And by then you have like 12 different ones, but you only really love one, and when you go to replace it because it finally died, they don't make it anymore.
Also realistic looking/feeling (yeah right) or hard plastic...
Maybe you just want to go the Hitachi Magic Wand route, and get an attachment for it... Or do you want the one that pulses to the beat with your iPod? Or, the one that goes off when your cell phone rings, or the person next to you's cell phone rings, or...
Then there's the sybian and its attachments, and... Oi, I know entirely too much. This is giving me a headache?
Oh right, ask a man forum. Unless you're insecure about your size and your ability to please your partner (male or female) they can be a nice and welcome addition to the bedroom. If they make you feel insecure, maybe you should find a therapist.
"Well, then," the Cat went on, "you see a dog growls when it's angry, and wags its tail when it's pleased. Now I growl when I'm pleased, and wag my tail when I'm angry. Therefore I'm mad."
