I wonder why this sort of questions is not asked in the Bike Mechanics subforum, where much more experienced people visit.

Anyhow, get this, this, this (the red one), these, this, this (may be a bit on the pricey side, but it's best of breed), and this. Get these, too.

That should cover your basic needs. I selected the best tools that are still affordable (no Rohloff Revolver 2, for example, though it's the best chain tool in the world).

You don't have to thank me (I know you wouldn't anyway - now get off my lawn!)
