They are not real rare, they are awesome pistols though. I've researched them and found them on the internet for around a $1000 NIB. I think they are still being made, not in huge quantities I would guess though.
If it's in mint condition, that would be a great price. The HK soft case goes for around $200.I am too interested in this. There is one for sale locally that has the soft case, Novak raised sights, and 4 eight round mags for 1050.
