Hi and
to the forum.
I have a WM 151cm C cup TPE girl, Rachel, who weighs 29.5kg and she's no trouble at all to lift, carry about, pose etc.
I have three TPE dolls with a fourth on the way. They take turns lazing in bed and the others stand around dressed, either in my bedroom or living room. They sit with me when I watch TV, sit or stand near me while I'm working (I work from home), and regularly take part in photo stories.
My favourite UK vendor is Cloud Climax, I've had three of my dolls and a spare body from them. The website is a bit of a pain with bits jumping around and popping up, but I've always had excellent service from them.
With the 1/6 scale dolls, I have a Jiaou, similar to Phicen. There are plenty of those on eBay brand new from online shops.
