Tracking clicks on site

We are looking for a way to track click throughs from our site to our clients sites so that we can monitor clicks at a glance rather than having to look at the stats for each individual site and check the referrer info, etc. We were using a service from linkcounter.com but they seems to have just stopped the service (it was free!) so I've had to spend this morning changing the links back to direct to the clients sites rather than the diverted ones via their tracking system!!

We then thought about creating a page on our site for each client and have the links divert to that page then redirect to the clients own url but we are worried that it will put visitors off as a refresh in the head will work once the page loads and although there isn't much on the page the tracking system in place for logging that page is there and so visitors may be sat with that page for a wee while, or if we use a javascript redirect which would be quicker for the visitor it may get the site in trouble with the search engines who are picking up on that kind of thing as spam!

We would prefer a solution that doesn't involve a third party as their server downtime affects the click throughs working and can, as we've found out now, just close down for good!

Any thoughts gratefully received
