It depends. There have been some nice custom offerings over the years from custom artists Rainman, Velvet Morning, and Iminime, that initially ranged in price from around $500 to upwards of $800, but are now generally much higher than that. There is one you can find pretty easily available for pre-order from many large retailers now, for around $150, but I would urge folks not to support that release, since they are using a counterfeit/recast of a custom sculpt previously made. You could also build your own figure out of available parts. There was a sizable thread on the forum dedicated to helping people do that, but I can't find it on a quick search.
