Soldering iron for vinyl BJD

Hi! I've been wanting to modify Dream Dollfie heads for a while now, and have been watching a lot of videos regarding them.

Whilst watching them, I recognised that nearly everybody was using the Hakko My Pen Alpha.

I wanted to buy it, but saw it was dangerously incompatible with where I live, since it uses 100V while I live in an area that uses 230V.

Does anybody have any recommendations or experiences with other soldering irons that has worked well for them?

I'm a bit worried about getting something that'll damage the doll itself.

And otherwise, any tips for modding? :)
