If you want to get no squeal, go for OEM pads. If you are prepared to put up with a little, then there is a wide choice but be warned of 2 things. First, it appears that the same type of pad can squeal different amounts on different cars. Second, what is acceptable to 1 person might not be acceptable to another.
As an example, take Skeletor and myself. Both of us fitted Pagid RS4-2 pads. I get a little squeal occasionally at low speed but IMO, very acceptable. Skeletor got loads of squeal which he found totally unacceptable. The pagids stop the car so much better than the OEM pads and I am as happy as I could be while Skeletor removed the pads and wasted £177.
For every person who will tell you that a particular pad doesn't squeal, you will find 1 who says they do! Good luck with your choice.
