So what tools have you purchased and thought for ages after what hassle it has saved you and how glad you are you got it to make your life easier?

One of mine is my Snap On impact gun. Want to know what little tools there are which i could buy to make jobs much easier for myself as when i play its a hobby its not a job so not aware of the gizmo's available.

1 thing i am after is a tool for the clips usually found on coolant hoses with the 3 prongs. They are a nightmare and i have seen a handy tool which is remote on an extension which you put on the clip and clamp with the other hand a few feet away looks so much easier than the trusty pliers i use which are a nightmare in tighter areas.
