Have you tried the Mapdex Toolbar

I need to credit James Fee (http://www.spatiallyadjusted.com/) for a tip about this one (although I've been a mapdex fan for a little while)... Mapdex is a global index of 1,781 servers, serving 32,433 map services, containing over 400,000 GIS Layers, covering more than 4,000,000 columns... now you can add a toolbar in ArcMap providing direct access to the service - http://www.mapdex.org/MapdexToolbar/
