There are resin busts like this, too. But they are more expensive (around $100) and a lot of them seem to be limited. I almost bought one or two off eBay before I realized they were actually recasts of limited bust stands from Doll Chateau or Dollzone. Luckily I did a little more searching and the eBay prices clued me in (about half the price a resin bust usually sells for).
So, 3D printed bust stands are good alternatives. Much cheaper ($25 to $40 depending on where you buy them). But they’re also a little harder to find. The two I got from an Etsy seller were actually smaller for MSD although I thought they were for SD. It’s fine because I needed an MSD one. The one seller I got the first one from seems not to make them anymore, which sucks because it was the perfect size for larger SD heads and it came with elastic and O-ring, whereas the smaller ones I had to provide my own.
I think there are also files for 3D printers to download and make your own stands, but as I don’t own a printer that doesn’t help me. My nephew does, but he lives ten hours away from me. lol
