We've been using it for the past few years and not the most happy with it at the moment. Is there any good alternatives out there?
Trac provides a very nice interface to Subversion - I prefer it to the WebSVN views.
In addition, it adds many other features, as well.
I'd give Warehouse a try. It looks very nice and should come with the same feature set as WebSVN.
I highly recommend Atlassian's FishEye.
It's a fantastic product.
The only downside (if you can call it that) is that it is a commercial (not free) product, but if you happen to be working on an open source project, it is free.
You can see it in action if you check out the Spring Framework open source project.
ViewVC is another popular one. If you install the CollabNet Subversion Server, ViewVC can be installed as an optional component.

The Subversion Project Web Site also has a list of repo browsing tools
Check out InDefero, this is a clone of GoogleCode available for free.
