Looks like Bud's had one for $600 NIB. Apparently you're going to add $50 to that price to get him to ship the gun through an FFL and then you're going to have to add another $30-$50 on your end for your local FFL to the paperwork where you are. So now you're around $560. For me, the extra $40 to know I was the only one who ever owned the gun is worth it, but it's your call.
Now if it was a face-to-face deal where you can see and handle the gun, I'd say it was a no-brainer and go for it.
