I've seen worse. Repainted BD Mark 85 for $2000 by Owen. It's a beautiful repaint but $2000 is insane.
I think my hard limit on figures is in the $1000 area for sure. The reason it's not as bad from Inart compared to custom sculpts or figures I've seen is is that it's for the price of two figures with full rooted hair. Hell I've even seen a Breaking Bad Heisenberg for $2500 and a Hector figure for
$10,000.
It's a beautiful piece of work but there's not a single figure I would ever pay that much for. The figure better be paying rent if I bought it for that much.
It doesn't seem that far off. All the top dogs in the custom field are charging close to a grand for a custom sculpt + paint work. I know nightt47 charges about $800 for his paintwork on sculpts.
