The Cold war commemorative looks pretty cool. I played with one at the LGS. The price was a bargain. I'd be tempted to make it a shooter, but that's me. I'm no expert on gun values, so I can't say if it's one that will be worth a fortune in 25 years. I already own one commemorative that I can't realistically shoot, I won't own another. My 75Db is a very nice shooter. Comfortable, accurate & reliable. As a bonus, the Kadet kit works like a champ as well.
The Witness is a joy to shoot. Nearly as good a shooter as my SA Trophy Match at less than half the price. I like my 1911, but this is a pleasant change. I've only had it for about a month, so I can't speak to the long term durability.
