I know that internet connection speed tests aren't all the same, but how can I find one that'll give me accurate results? I'm comparing Comcast cable to AT&T DSL to find out which's faster where I am, in southeast Michigan. I dunno if this belongs under internet in general or internet technology, so I just picked one.
