Normal Phone Ringtone

Is there any way at all to get a ringtone on my iPhone that just sounds like a regular, classic cellphone? Marimba doesn't sound like a normal ringtone at all. Before the iTunes update, I had the CTU24 ringtone, which sounds a lot more like a phone than Marimba does. I'd even be willing to buy a normal sounding ringtone, even though I'd be flipping angry about having to do so. Any solutions?
