How often does a residential septic system really need to be pumped out?

I'm getting conflicting opinions on how often a septic system needs to be pumped, and pumping isn't cheap. My current system is about ten years old, and it's been mostly just me using it. I've heard of other low-use households that have been pumped maybe once in 30 years. Conventional wisdom seems to be thus: pump every 3 years or so or risk anything from a bad smell to a total system wipeout and replacement. Is that for real?

Of course there are variables like tank size and usage rate and whatnot, but is this "every 3 years or else" rule of thumb really true? Could a low-usage household really hold out for 30 years, or even indefinitely? Could allowing it to overfill really destroy parts of the system? Lastly, what is a ballpark fair price for such work?
