I use the cheap stuff from autozone and it works great. It is red and comes in a bottle of about 6 oz. More than I'll ever use for $3. I did learn from this site it is best to let the paste "cure" for a while before applying the brakes: For example overnight. Otherwise the paste just squirts out of the places you need it. I had to do mine twice because I didn't allow it to cure the first time.
I would suggest using more pate than you think is just enough to do the job. Also, I used some Berryman's "Brakeklean" to flush out the old anti-squeal and dust from around the pistons before reinstalling the pads and shims.
I like to really clean the inside of my rims when I have the wheels off the car, too. Go ahead, call me anal.
