PK,
I bought a dan Wesson pistolPack back in the early to mid 80's. It was the Dan Wesson pistol pack model 15-2vh if I recall correctly. It consisted of the gun, a 2", 4", 6", and 8" barrel, two grips, target and combat, a carrying case, tools, including a thickness gauge for gapping barrel/cyclinder fit, a belt buckle,and patch, along with all booklets and instructions.
The price through SHOTGUN NEWS at that time was $375.00 less shipping and FFL receiving fees.
What I thought at that time and still now was a GREAT buy.
I still have the entire package and wouldn't consider taking even $1800.00 for it (which was offered once a chunk of years back.)
The value is whatever you are wiling to give for it and how bad you want it.
A time or two in the past I have given more than what the fair price should have been for an item, but I really wanted the item at the time and do not regret for a second spending the extra cash.
So,all though the $900 sounds too high to you, it will ultimately rest on how badly you want the item and how willing the seller is to bend on his price.
My theory on selling guns is that if I don't get what I want for them, I keep them.
Once I've bought them, they don't cost me a penny to keep. Since they don't need to be fed or watered, and I don't have to rent them an apartment, it costs me nothing to keep them. Although I HAVE refretted selling a gun or two. I have never regretted keeping one.
Just decide how much you want the item and go from there.
My Dan Wesson earned me an "EXPERT" award for pistol marksmanship in the Navy right out of the case without ever touching the sights.
It still shoots circles around my buddies Colt Python.(of course that's when HE'S shooting it.)
On this matter follow what your heart tells you, and pay what you think is fair.
If there are as many pistol packs out there available for as little as everybody is saying here, I may look for another one myself.
Good luck.
