What type of CB antenna should I buy for a handheld radio?

I have an early 90's style radio-shack handheld radio, and an antenna mount. Is there a specific type of antenna I should buy? Is there anyway I can buy it and set it up without spending a fortune? And I read that you need to tune it using a SWR meter, I obviously dont have one, and is there a way to tune it without using one?
