I've got a 75BD that I got years ago.. still one of my favorite guns to shoot. I paid $279 NIB for it at an online retailer... $25 shipping, $15 FFL fees. Only thing I've done to it is added a Hogue rubber grip, and bought new recoil springs. Gun shoots like a dream and I can't recall it ever jamming.
The SP-01 has been in my eye for a while.
Would love to see a pic of the old BD.
