Been searching around and have found Topeak brand of quick release racks and bags for my commute to work (specifically the Topeak beam rack, I've still got to figure the difference between the A-Type, E-Type and V-Type but that's another story)

What are some other quick release options to consider??

Things I'll have to carry are Work Clothes in the morning (with shoes) and lunch. Sometimes I'll have my laptop but I can put that on my back with a backpack. 8 mile commute
