It depends on how advanced you want:
1) Inflatable dolly. Sort of like the VCR of the industry now. Only remaining plusses are that they cost around $100 and you can hide them rather effectively when you have company.
2) TPE-Silicon “real dolls”. Lifelike appearance and anatomically correct but no talkie. $800-$2000.
3) Robotic doll. Adds AI and electronic sensors to the doll so it actually “feels” and “thinks”. A few also have limited motion. $5000-$20,000
4) Full motion robotic doll with AI and sensors. Performs menial tasks as well as bedroom chores. This would be the “Ferrari” you spoke of and it is not really on the market yet but there are several firms trying to get there.
I guess that’s what I get for being married to the real thing for the last 24 years. I had no idea about the state of the art of sexbots.
Thanks for the info.
