IMHO, DIYers will eventually "give up" DIYing if they don't invest some of the money saved into tools.

Nothing more frustrating then a 3 hr job turning into a 3 day one because tools are lacking.

I upgraded my compressor ($300) and bought the gorilla impact gun ($100) to install a new transfer case chain & seals ($100). This turned a $100 job into a $500 job.

Huge repair cost jump, but the BMW dealer would have charged almost $3000 for a reman TC unit and over $1000 labor.

Future DIYs will be much quicker/less frustrating. Almost enjoyable!
