I have also been looking for a bike computer that allows you to download your data. I have been searched google and this forum, but I can't get anywhere since words like download and computer bring up a lot of other sites instead. What I'd like to get is something basic like the Nike+Ipod that I have for running. I only need the standard features (speed, distance, time, etc) and the ability to store and manipulate the data.
The Garmin Edge actually looks pretty good for only $220. I'd still like to find something cheaper. I guess in my mind, I wouldn't think that it should cost so much more to include a memory chip in a standard bicycle computer.
