Star trek ringtones-where to buy for iPhone 4s?

[ECGcrackberry]

I am a newbie and have never bought or downloaded a ringtone before so I would like to respectfully apologize if these are stupid questions.

I would like to add to my new iPhone 4s star trek ringtones such as the ring of the communicator on the original series or the red alert warnings from the original series and the next generation.
Does anyone know where I can buy them for my iPhone and would not crash my phone. I am with Verizon.

Thanks in advance.

You can buy from iTunes. There should be a Tones section on the more tab. Or you can create your own or look for the specific sound effects. The file you want to use are .m4r format.
