I've used a tool called Cirrus Configuration Management from SolarWinds.Net in the past. If you have other devices besides just Cisco this is definitly the tool of choice. They can make it work with nearly any device as long as it supports a CLI.
This tool has a seriously easy to use interface and will also allow you to save the configs and run reports against them to see where it changed. This makes it great for SOX compliance as well as many other security and reporting features.
I'd recommend it as its highly customizeable and requires nearly no time investment. Plus it will still be useful if a decision is made to move away from the Cisco Products.
