Where Can I Buy Vibrators

My husband thinks it can be fun to buy a vibrator. What is a vibrator and where to buy one?
I am married and have a healthy sex life. I was once told that vibrators were used by people that dont have sex. Can someone please fill me? The vibrators are good for sex life healthy married couples?
I recommend Doc Johnson Lucid Dream 48 .. http://www.amazon.com/Doc-Johnson-Squirmy-Vibrator-Purple/dp/B000FEPPQK/ref=sr_1_4?ie=UTF8&s=hpc&qid=1268846214&sr=1-4&tag=ay-buy-20 I was so excited to get this, but when I did I could not figure out how to turn the damn thing! There were no instructions with the subject and docjohnson website was not useful. It was so frustrating! It is the secret lies in holding down the circle button on the center for a few seconds and, apparently, a light is supposed to flash (mine did not) and then you can push up or turn the vibe up button should launch! It worked for me, minus the initial light. After that it worked very well! Very Happy with the results!
I had a "rabbit" that broke and this seems to work even better! Highly recommended!
