That’s the better route to go. It’s probably cheaper than trying to buy a parted out HT Sith eyes sculpt, or getting this figure at an astronomical price then trying to get a parted out regular HT sculpt.
Though if it were myself, I’d probably just wait for a KO sculpt on OSK at $30. I’d have the regular Anakin figure and a Sith eyes sculpt for roughly the same price as this Sith version figure.
Certain figures I don't mind having two versions of them. The Anakin I knew I only wanted one, so I liked the idea of having him as dark side anakin posed with ep 3 Obi (when it finally arrives down the road).
