Hamano, Kelii, Ohana, Kala, Tangi, Koa Pili Koko, Mele, Pono, Mainland... the list goes on but that's off the top of my head. There's plenty more.
That's actually a good price range for a solid wood soprano. Hell, MGM's got a solid koa Tangi soprano for under $250 shipped. It hurts me to see it. (must resist...must...re..sist...)
