Hi,

I am looking for a rack for my commuter bike. Can anyone tell me where I might find information on the various designs, and were I can find the best prices online? I've seen racks that have pouches down alongside the rear tire, and also ones that site above the wheel. I'm not sure what the advantages/disadvantages are of those different designs.

I will be carrying a laptop and sometimes a book or two and some papers. I might also want to throw some lunch and/or a change of clothes or whatever in there. I would want something that isn't too "jarring" to my laptop - not sure if that is possible or not.
