There are some excellent articles and other info on this topic at 
http://www.thekrib.com/Plants/Tech/ and 
http://aquaticconcepts.thekrib.com/. There seems to be a lot of argument 
over whether cable heating helps or does nothing useful. I lean towards the 
"better long-term stability" argument (and I think the cable heaters do a 
good job of evenly heating the tank and thus avoiding hot and cold spots in 
the water) myself.

I'm not a big fan of the line-voltage (120v/240v) undergravel cables, but I 
think the low-voltage cables can be helpful. I haven't heard of many 
problems with the cables breaking provided the cables are suitable, which 
usually only applies to DIY cables that were made with unsuitable types of 
wire. If you want to DIY a cable I can offer some advise but I'll save the 
bandwidth until asked ;-)
