I would highly recommend the Jopen Vr6.5, or the Vr.5.5. I'm so not a rabbit girl, but I love those two.
Jenn recommended FiFi above... I have Fifi, and it's pretty good, but I'm not sure I'd agree that it offers direct contact. I really don't get much clitoral stimulation from that at all unless I push on the ears (which don't have much flex at all).
