I'd gladly pay $100 or more a pop for figures with Hot Toys bodies, Sideshow sculpted heads(in proper 1/6 scale, no overcompensation for "shrinkage"), Hot Toys quality accessories, Sideshow outfits(though slightly better quality- leather or pleather boots).
If it was just more complicated but otherwise normal Sideshow figures with smaller production runs, then no. I mildly resent paying the prices for Japanese figures, although Hot Toys is the easiest to swallow for me. There's no perfect 1/6 company though.
-Sideshow has the best licenses, the best prices, the best headsculpts, the best paint schemes(sometimes undone by the production process), but the worst bodies, average-to-cheap accessories, and too big heads.
-Medicom has great licenses, great outfits, great articulation, bad sense of scale(usually, maybe getting better), relatively plain paint schemes, next to no accessories, and outrageous prices(relative to the competition).
-Hot Toys has great licenses, great outfits, great bodies, great accessories(if a tad too much reuse), good sculpts, poor paint schemes, and expensive prices.
-Takara's best licenses are shared by other companies and the rest obscure, they have great outfits, okay accessories, okay headsculpts, great articulation, expensive prices.
The majority of Sideshow's 1/6 output is pretty damned good, even at this pricepoint(although that's creeping up all the time) so I don't think there's much need for a separate higher end 1/6 line. Even if they did start such a line I wouldn't expect them to fix the flaws I mentioned above in it.
