This is why I'd like to see a new design in .30 Carbine (and probably 5.7x28mm as well), perhaps something along the lines of the Kel-Tec SU-16, Ares SCR or a basic Saiga. I don't mean just chambering one of those in .30 Carbine, which negates the advantage of the smaller cartridge, I mean a modern polymer and metal gun designed around the cartridge. That certainly should not cost $900.
With regard to the 5.7x28, what you're describing sounds exactly like the p90/ps90. That weapon was designed specifically for the 5.7x28 round. The ps90 is 26" in overall length and weighs 6.6 pounds when loaded with 50 rounds -- hard to get much lighter/smaller than that.
