Yes. I would be able to get the experience of a relationship without the bad sides. No nagging, no complaining, no worries about loyalty or hypergamy. For what its worth, a sufficiently sophisticated sexbot/wifebot would beat many romantic relationships today. You would essentially be treated like chad by the bot.
It wouldn't be $200, and it would need quite a few features to make it a worthwhile purchase over a doll. The ability to move (both body and walk), respond to verbal, visual, and tactile stimulation (smell/taste would be nice, but not necessary) and carry sufficient day to day conversations about various topics beyond sex would be the minimum. I would like it to be able to do housework/cook and possibly even look after kids. Greet me at the door when I come home from work. Maybe make her software easily portable via smartphone so that she is always with me. Essentially treat me like a foid would treat chad.
I would be happy with it.
