The Yahoo Directory is probably the most important directory along with DMOZ to get into. It is very important. It is well worth the money. I doubt if you get much traffic from their directory, but your ranking will jump alot. craig http://www.IndianapolisSeo.com
I've tried getting in for free before, no luck. Can't see the value in paying honestly, most people I've spoken to about it says it gets very little traffic, however many claim it helps with page rank etc.
