What is the best Handgun to buy?

I was wondering what everyone's opinion is on the best Handgun to buy? I have been looking at a Glock 22 S&W 40 However I am open to any suggestions.. I am not really interested in revolvers however. Also, I was thinking I may want to use whatever I buy as a concealed weapon so something that would work for that. (small enough in size) I live in Utah. Please give me your opinion and why and how much it will cost me. Thanks in advance! -Lee
