Default Whats the best car diagnostic tool?

Last week I replaced my alternator. And it wasn't that hard, I saved 400£ by doing it myself. So I want to start doing tune ups, fixing minor things, etc in my car.
I am a noob, so I'll probably be posting here a lot. But I want to get a tool to help diagnose my car - like the one my mechanic has. What is the best one to get?

Thanks, Peter

EDIT- guys i found a site near me and it does free shipping too!!

If your vehicle is a 2006, you can buy a simple OBD2 scanner for 25 to 40 bucks, or you can spend a grand on one. It all depends on how much data you want to access.

For what you want a cheap code reader and the internet are all you need. I'd spend enough to get a quality unit.

Back in my Miata days, OBDI, the very best diagnostic tool was a bent paperclip.

I'd start with a basic OBD2 code reader and go from there. If you use it enough or run into things that it can't do, upgrade from there.

Keep in mind that most of the cheap readers can only communicate with the ECU and not things like the ABS, airbag or transmission modules. If your car has a CAN network (a 2006 probably does) then it may be worth it to spend a little more on a tool that can also scan for CAN network faults. A multimeter and a test light are also really valuable tools to have. Cheap ones will work just fine.
