You don't have the best one I know of listed: Testmy.net
It doesn't use flash (which has issues), and it allows you to use really big test files (50+MB), so you get past the dumb "speedboost" results that only kick in for the first few MBs. It also allows large uploads. Plus you can log in for free and track results over time.

As a result of writing this Page I called Comcast because my speeds seemed too low. A tech was just out here and found that the trunk line that serves my townhouse block was broken in half and only a tiny, tiny piece of wire was still connected. He replaced the connection and my speed is back up to 16Mbps, which is what I pay for, not 9Mbps.
