hello, I am new here, and I just got an sw9ve a month ago. I like this little gun. I have the rail for it, but am looking for a laser sight for it, but money is a problem. do they sell a cheaper sight?

this is the first semi-ato I have had. I had an old S&W 38 my dad gave me years ago that he carried when he was a police officer, sadly the barrel is shot out. now mom has it in the shadow box with his flag and medals.
