I've concealed carried both a Detective Special (w/ barrel shroud) and an older unshrouded Cobra. Preferred them to my S&W .38 M60. I liked the six shots better than five. Prefer Smith DA pull to Colt, but both are good.
The Cobra was my favorite out of the three; a joy to carry, good trigger, and didn't seem to be as susceptible to rust from sweat as the DS (because of aluminum frame?). It was as accurate as any other D or J snub. The Cobra seemed to be a perfect blend of weight, size, accuracy, and firepower. Excellent trigger. It was a beater ex-LEO gun and not especially pretty, but I wish I still had it.
If you find one, get it. It is still every bit as good or better than any current snub made by S&W or Taurus.
Just remember that it is not a heavy duty .357 framed package (like a Ruger SP 101). It was designed to be light and easy to carry .38 for close range use.
I priced a nice (85-90%) nickel DS in southern Ohio about 2 years ago for $445. I'd think that you might find a decent Cobra in the $425-$500 range depending on what part of the country you're in. Colt revolvers are scarce everywhere and anything in good shape under $400 is a great deal. I'd hate to pay anything over $500 unless I just HAD to have a particular weapon.
Besides, you won't lose any money on it if you hang on to it for more than a year.
