I use phonezoo for all my ringtones and my background photos. I love phonezoo.
You simply sign up for an account, give them your phone number (I've used them years and never had any spam from them, just watch for the 3rd party specials they put up, you can simply scroll down and say no thanks when they pop up), find the tone you want and have it sent to your phone, it comes via text. Then you simply listen to the tone and save it as a ringtone, not as a sound, at that point you can set them as your ringtone.
