Google Mini Search Appliance

Is anyone using the Google Mini Search Appliance
(http://www.google.com/enterprise/mini/index.html)?

We are about to redesign one of our websites and we're considering
installing this for our search funcions. We currently have six websites
but will have a total of eight by the end of the year. From what I've
seen it seems like it would help us greatly but I wanted to see if
anyone here has any experience with it and what you think?

Thanks,
