Admittedly I've only used two or three products, but for what you suggest you've got, I'd defiantly recommend ipClarity ( www.ipClarity.com ), its the best for ease of set up, and immediate results. When I subscribed to their service, i was getting web reports pretty much straight away, and it only took about 2 mins to set up. I'm pretty sure they have a US office now as well. Cheers
