After reading the yankeegunnuts review, I would have to say, at the bare minimum, to wait one year and see if Charter Arms works out the kinks. There will probably be many more reviews available to view during that time. Actually that's good advice on any new model of anything, guns, cars, computers or otherwise.
I have seen the Smith & Wesson Airweight .38 special for sale at my local gun shops for $349. That's a decent price for a "name" handgun. When my wife is ready to start carrying concealed, the S&W Airweight will likely be the handgun.
