Gotta agree here. If the KSG would consistently sell for the $650 Kel-Tec claimed it would (Series 70 seems to have lucked out), it would do a lot better.
Now I'm not advocating price gouging, but when the dealers are asking $1800 and can't keep KSG's on the shelf, I think it's doing just fine! Eventually, supply will catch up with demand, and the prices will come down to MSRP or below.
