I picked up a box of them recently and have put them back up for sale. While a serious bargain, the PSC soviets in 15mm are quite poor compared to the FoW minis I have on hand. That being said, I'm quite impressed with the later PSC germans and brits. Apparently the Americans and Soviets were some of the first designs and were scaled down 20mm figures (digitally shrunk). They have some useful stuff in the box though (medics, and unarmed figures, etc.) so it's a bit tempting to keep the box just for that.
Their 15mm PSC gun crew are similarly...poor, but usable.
You've done a nice job with them, considering!
