I am looking into setting up a tool box specifically for my bicycles (when they get here). Are there any tool kits/sets that have all of the needed tools? Am I going to be paying with two limbs and my first born for one of these sets?

What essential tools do I have to have right now to work on my bike? Are there any tools should I have while on the road? I remember doing everything with a pair of vice grips, channel locks, a hammer, and a flat head and it wasn't pretty! Thanks for the input.
