Needed one and its not bad at all. site as a geo db you can download also.

That's the one I use, too. Excellent features.
Having the ability to combine several logs is great.
Using the filters and only viewing the parts of the logs I need at the time makes finding the cheaters on my toplists a lot easier, too! :)
