If you want the best DA/SA 9mm for your money you will get an EAA (Tanfoglio) Stock 9mm. This:

If you can get this gun for anything under $650, you are getting a great deal. I have the same gun in 10mm. I also have a very nice glossy blue CZ 75B and a S&W 659 (2nd Gen of the 5906). Here is why I like
THIS Tanfoglio pistol:
Hard Chrome frame and slide - scratch resistant, rust resistant, durable and attractive;
17 round capacity; magazines are highly polished and exceptional quality also.
Trigger - hands down the best DA/SA trigger out there on any production gun; better than the one on my CZ 75B. I might be able to upgrade the CZ trigger to get it as good as the Tanfoglio, but out of the box, the Tanfoglio is superior
Cone barrel/slide lockup - gives exceptional accuracy
Back and front strap checkering on the grip; also nice set of wood grips comes with the gun
The internal parts are excellent quality - great fit and function on all parts; also great slide to frame fit.
A Sphinx AT 2000,
might be as good as this particular Tanfoglio. Good luck trying to find one of those for less than $1,700
