The Star Model B is now listed as going for from $100 to $300, depending upon condition. So the average is around $200 for Good Condition guns.
I've owned and carried a Star PD for years, and wouldn't give it up for any reasonable amount of money. It's not completely bulletproof, though, because the manufacturer's heat treating is suspect, and the gun's sear has a reputation of being too hard and breaking unexpectedly.
I shoot it a little, but carry it a lot. It's a lightweight, very small, very accurate .45, suitable for self defense.
I like it.
