From my understanding a quality silicone love doll cost between $1,200 and $2,500. They come equipped with 2 USB rechargeable heating rods so you can heat the love holes. Proper cleaning of the unit is a must. I think some parts of the unit are replaceable and if they aren't that does pose a problem over time obviously. I would think being very gentle is also a must. I'm going to store mine in a metal gun cabinet so no one knows.
