What instance size are you using for your agents? The micro instances would be great if they were more specific about the CPU capabilities but I get the feeling that "short periodic bursts" are not sufficient for running IE and getting stable results but I'd love it if it does work well.

All my agents are win2003 spot micro instances. I only run 1 thread per instance and seem to be getting good results. With the spot instances my average cost per agent is about $15/month.

I haven't verified the consistency of the results on micro instances yet. But they do seem to be sufficient for monitoring trends.

Attached is a waterfall from one of the micro instances compared to the same page pulled from webpagetest dulles instance. Notice the CPU utilization.

It would be nice to further confirm the numbers being produced by the micro instances.
