I found a Camillus USA Cuda Quick Action for $24 in the store here, and immediately pounced on it; as I've been wanting one for years, but was priced out of the market. It must have not been listed long ago, as it wasn't up before lunch.
According to a 2003 catalog, this is a Cuda Quik-Action Jr. (just over 4" closed compared to the full-size at 5") Spear-point. ATS-34 blade and G-10 handles.
Aside from the simple Medium Sierra lockbacks (which I like for around the house--plus, they can still be had new for MSRP), I think this is the first "tactical" Camillus that I've got. This one operates similarly to an automatic--slide the button forward, and it opens. Since it's beat up, it will become an EDC. I'm sure this thing will be a dream in the cold weather with my gloves on.
Will need to get more Tuf-Glide. I've found that most of my newer folders (CRKT IKBS knives especially) just gum up when I use 3-in-1, but Tuf-Glide allows them to become pretty smooth. Having to go over my late grandfather's collection and forgetting to put the cap back on a few times made it go much faster than expected.
