How do you know the first one isnt an original DC Viking?
The last one, the pics dont do it justice...trust me. He started out at $1000...but eventually traded it for a Deffiant II. Basically he got $700 for it. I bought the last one new from DC.....$1250 for them new back in the day. So $700-$800 for one now.....is definatly worth it, no matter what color. ALso the last one had tons of stuff with it, CP barrel, tool kit, blank warranty card, 2 bottles of aka lube , V-link, Pandora board, Tadao board. ALl that extra stuff makes it worth alot more.
Back OT.........Any thing you pick, you need to shoot first if possible. All of the choices you have named will make great guns.
