From an investment standpoint, I acquired a CZ75 short rail, made in 1977 and mint condition, for about 1/3 what it might sell for (the price was so good, I can't bring myself to tell it, in case I DO sell the gun). From a user standpoint, I got a Walther PPS for $350 recently, and a Glock 29 OD green for $425, but both of those are so fine, I would buy them again at retail or better. To me, they might represent the best of the best for concealment and defense, based on performance and accuracy.
