Everything about it is usually expensive. Most importantly, love dolls over 150 cm are too big for most companies, so prices will rise.
Although sex dolls look the same on photos, they use many different materials. Up to about $500 is usually an inflatable doll. The $500 to $1,000 is usually sold for smaller dolls with low TPE and the real TPE doll for 1,000 euros.
There are different types of betrayal of TPE dolls. Cheaper sex dolls usually use a slightly harder type and require a lot of maintenance. More expensive brands such as WM, SY, JY and tpe dolls use a smooth, soft version that feels more like leather.
