When my wife and I used to go to swinger's parties up in Oregon, somebody always brought one. Most of the girls that tried it came in buckets, so intensely that they had to stop or get off. They usually had a guy there working the controls so that the girls didn't have to trouble themselves, and of course he got to watch. There are different heads, different speeds, and different movements such as a small circle, etc. I "heard" that it cost about $1200. I would offer one piece of advice to anyone planning on having one. They can make quite a bit of noise when running, loud enough to tell everyone in your apartment building or motel what you're doing. The best setup is in a separate, single family dwelling. Ciao.
