Is there anything cheaper than this toy that is similar?

OhMiBod is one of the cheapest with the music functionality. You might want to use it for a test run. The wires would annoy me personally so I'm saving up for the Freestyle.

Unfortunately I think the cheapest option that you have if you want a vibrator that works in time with music may be the OhMiBod Club Vibe, it's their small bullet vibrator designed to be tucked into your panties and worn around. However it's still $49.99 for such a little thing while the corded OhMiBod is 59.00. You may have to take a chance and spend the money if that's the thing that you want.

Wow, that's expensive! You may just have to wait for another good alternative. The OhMiBod is cheaper, but I've read it's not for everyone. Maybe they'll come out with a better product. Or you can contact the company through EF (I do believe) and let them know how you feel about the price of this one.
