My favorite MultiTool so far has been the Topeak survival gear box. Saved my ass last week when my chain broke. I normaly HATE the chain tool but this one worked decently, the long lever screws in the bottom to give you a nice hand hold. It is a bit larger then some but still not big. And has everything in it patches.. tire levers a bit smaller but they work, allen wrenches etc.. And it is on sale at nashbar for $15.
