I've been using tools like this for several years and I can say I watched the video, tried the online demo, and then looked at the prices and the pricepoint turned me away immediately.

I left woopra because it was too expensive as well and now use chartbeat ($10/mo for up to 1000 concurrent), reinvigorate ($10/mo w/ coupon for 1 million pageviews (though it doesn't actually limit you there I don't think), $20 otherwise I think), and statcounter (free).. oh and google analytics does real time now too for free.
