Alright, so I've been buying a decent amount of tools lately. I got a chain wear indicator, chain cleaner, chain ring nut wrench, crank arm extractor, and probably some other things I'm forgetting. I'm thinking instead of just buying the individual tools, I'd probably be better off buying an already made tool kit, like a park tool ak37.
I'm just not sure if something like that is necessary though. I just got a craftsman 160 piece toolset at a sears outlet that has both metric and standard wrenches, plenty of metric and standard sockets, and some different screwdriver bits. Then cyclegear had mechanics allen wrenches for $10 bucks, so I picked up some of those as well. Should I still spring for something like the ak37?
I still need spoke wrenches, a cassette brush, bottom bracket lockring wrench, chain breaker, pin spanner wrenches, a better chain tool, etc etc.

Would I be better off buying a big premade set like that, or just building up my own since I already have a few bike specific tools, and normal everyday tools?
