click tracking script needed

[stevebrett]

I have a client who's just begun to place some paid for banner adds on their site. They'd like to install some soft ware so that they can provide click through statistics to their supporters/advertisers. They are a non-profit so free or very low cost would be desirable.

I see there are quite a few such scripts and even hosted solutions around, but as i have no experience with any of them i thought I would ask for a recomendation or two as i begin my search for them

Thanks in advance

OpenAds / OpenX are probably the best solution for this.

It is pretty complex software, so it may have a steep learning curve to it.

I used it back when it was PHP Ads New and was impressed by it, and it has only gotten better since.

That looks like an excellent product but way too complex for this use. I'll keep it mind for other projects though. Could any one could share their experience with something a bit simpler?
Thanks
