I exclude the home sets by using the "Basic Search" function at the starting Chips page. Check the "only" and "titles and descriptions" boxes and in the seach box type a minus sign and a parethesis with no space between. Enter the key words you wish to exclude seperated by commas and end with the other parenthesis. Good key words to use to get rid of the home sets would be 11.5g, case, and table. Your entry could look something like this:

-(11.5g, 11.5gr., 11.5, case, table)

This works pretty well for me... I used to include "vegasclarks" but I don't have to do that anymore!
