PWS CQB Comp Alternative?

[tonhe]

I'm looking for a lower cost version of the CQB Comp by Primary Weapon Systems. I've heard great things about it's design, and ability to throw sound forward which is a rather nice feature for SBR / AR Pistol users.

I just can justify the price!

I'm only aware of two-- the Noveske KX3 and Spike's Tactical S.T.A.B.

The Noveske is priced near the PWS. I'm not sure what a used S.T.A.B. goes for these days.
