I think the reason why everyone wants another luke,whether it be a Bespin or ROTJ black suit version or whatever is because the last two sculpts weren't that crash hot(Tattooine/Dagobah).
The only two Sideshow 1/4 scale Star Wars that I don't have are the two Lukes,I'd rather wait until he is released with a lightsaber.
I just don't find the other two interesting enough.
I can't help it, but every time I look at the first version of the Tattooine Luke I keep thinking of E.T. Those hands look terrible.
